Observatory 12: Griffith

In my last entry I described the day I arrived in Los Angeles, including my visit to the California Science Center. That was a Wednesday, August 29, 2018. The next day, according to my journal and my now vague memories, was spent doing laundry, getting groceries, and watching Netflix, a luxury with which I was pretty unfamiliar at the time. Doing laundry was also a luxury, as I didn’t have the opportunity during my week in Arizona, and my last attempt was that time in New Orleans when the machine flooded the kitchen in my apartment. Good times. This was a much better experience than that, entirely without incident. But that’s not why you’re here reading this! So let me tell you about the next day.

Griffith Observatory – Short Form

Here’s what I wrote in my journal a week after I left L.A., then I’ll add some details after that.

Griffith Observatory [is a] classic science center from the 1930s with a huge underground gallery added in 2003. Saw the sky show and got to look through the 12″ Zeiss refractor at Saturn. View was nominal, expected for look over LA, but still glad to have done. Four moons visible, Cassini Division, disk shadow. Stood in line with Gita, a science teacher from India. She was fairly knowledgeable about many things, some more than me, some less. She had never seen a planet through a telescope. I think she was a little disappointed at 175x, but that’s how it goes. There were a lot of people there, which is heartening. Lots of adults.

Griffith Observatory – Long Form

The Approach

I’m sad that I didn’t write more in my journal, and I’m sad that I haven’t written up my memories before now, because things are getting pretty foggy after two years. But let’s see what we can do here. I was not really familiar with Griffith before going there, so I didn’t know what I was getting into. Well, that’s not entirely right. I had explored the website, of course, so I knew it wasn’t a research facility. And I knew that they had public telescope viewing every clear night. What more do you need to know? Let’s go! Sundown was about 7:30 p.m. local. Since I wanted to do the viewing, I knew it would be a late evening before getting home. Consequently, I wasn’t in a hurry to get there when the doors opened.

It wasn’t very far from my apartment to Griffith, about six miles, but decided to take a Lyft. It was about 4:00 in the afternoon. My driver was an interesting young man, a musician and song writer, as it turned out (hence a Lyft driver?). When I told him I was a pastor on sabbatical, he said he was a PK (“preacher’s kid”) and had learned his love of music in the church. That was cool. So after that pleasant drive, I was in the parking lot. The Griffith is a beautiful building to begin with, but there’s also the view. Griffith Park is in what I think is the Hollywood hills. One reason I think this is you can see the Hollywood sign just opposite the observatory! It was surprising to me to have these lovely, rugged, sort of wilderness hills overlooking one of the most populous cities in the world.

Art Deco. Very nice!

The observatory itself is, again, the beautiful, white, art deco building with a decorative dome and planetarium dome in the center and observing domes on either end. There is a monument in front, also art deco in style, commemorating six great historical astronomers. The approach to the front door also has markers in the sidewalk showing the scale distances of the orbits of the solar system planets. There were quite a number of people of all ages milling about outside, making their way in or out. I was excited to see the inside, because the outside was such a pleasant start.

Remember the Buhl!

Inside, the Griffith Observatory is a classic planetarium. High ceilings, subdued lighting, two main wings for displays and the planetarium / sky show theatre in the back. It reminds me of the Buhl Planetarium in Pittsburgh that I loved when I was a kid. Another similarity is the Foucault pendulum in the lobby. This is a 19th century experiment in which a pendulum, free to swing in any direction, with a very long cable for its arm and a large bob demonstrates the rotation of the earth. The pendulum thinks it is traveling in a the same plane with each swing and wants to do so, but it is actually moving in a slight arc as the earth turns under the pendulum. This is proven by a circle of little pegs set up on the floor that the pendulum very slowly knocks down every so incrementally.

Anyway, the one wing had a variety of telescope models, replicas, and displays including a replica of Galileo’s telescope and a Faraday cage with a big Tesla coil, and the other had various science-y alcoves, ending with displays about the sun. This part is under the solar observatory/coelostat in one of the two domes on the roof. There is a large screen showing an image of the sun’s surface, which unfortunately was blank because the sun was in the minimum phase of its 11-year activity cycle. I enjoyed exploring all these displays for some time.

I took in the sky show in the Oschin Planetarium at about 6pm, as I recall. It was a pretty standard planetarium show with digital images, star patterns, and whatnot projected on the dome with dulcet narration. I don’t really remember the content, just the pleasant contentment of sitting in the big comfy reclining seat in the dim light, digging on the science, and feeling nostalgic about the whole planetarium experience. I always love the giant spider projectors, again, going back to Buhl Planetarium in my childhood, and more recently in the Hopkins Observatory in Williamstown. This one, like many such, is made by Zeiss.

The Zeiss star projector in the Oschin Planetarium, not quite as buglike as the older ones were.

Space, Underground

Had I visited Griffith in my youth, that is all I might have found. Some years ago (2002-2006), though, they underwent a major renovation by adding an enormous gallery and a second theatre underground! They actually have a movie about this in the underground Leonard Nimoy Event Horizon Theater, which I watched dutifully and enthusiastically. It was a fantastic engineering project! They didn’t want to change the beautiful original art deco building, and since it is perched on the edge of a hill, there was no room to expand outward. Their only option was to go down. So they had to figure out how to dig out a cavernous space under the building while artificially supporting said building so it wouldn’t fall into the new hole. This they did successfully! The result more than doubled the size of the facility. 

The Big Picture in the grand gallery downstairs. It shows a bit of the Virgo Cluster of galaxies.

Much of this space is given to the cosmos beyond earth, so the solar system (displays about each of the planets and whatnot, with scale models hanging from the ceiling) and beyond to far-flung galaxies and discussion of cosmology. The entire back wall is a single photographic reproduction of a section of sky that includes the Virgo Cluster of galaxies. According to my notes and a short film telling about it on the floor of the gallery, it is the largest such astronomic reproduction in the world and includes millions of galaxies and hundreds of thousands of foreground stars. The whole area on the sky can be hidden by your thumb at arm’s length. This is brought home by a sculpture of Einstein sitting on a bench holding up his thumb to do exactly that. It is a remarkable display, and all the more because they have telescopes on the balcony that you can use to look at it as if you were under the night sky. I found this to be very cool, as I have explored that region of sky with my own telescopes.

Into the Night

Sunset was about 7:12 p.m. on September 5, 2018, with astronomical twilight lasting until about 8:30 p.m. I don’t remember if they said when the viewing through the big telescope would begin. I do remember getting something to eat at the Cafe at the End of the Universe (with a tip of the hat to Douglas Adams). I’m not sure if I did this before or after looking through the telescope. I think it must have been before, because the time stamps on my pics shows I was at the telescope at 8:52 p.m., and the cafe closes at 9:00, as does the gift shop. I distinctly remember eating in the cafe and then going to the gift shop for some time. I also remember that there was not much available at the cafe other than grab-and-go stuff like microwave hotdogs, which I think is what I had. This was somewhat disappointing as meals go, especially since the cafe is listed under WolfgangPuck.com. I also remember that some staff person was mopping the floor and putting chairs up. My reconstruction is that I was eating at around 8:00, well after the dinner rush. It was a disappointing meal, as I said, also because I was really hungry. It had been pretty long since lunch, and I had been burning a lot of calories in walking and braining. Afterward, as I said, I went to the gift shop where I bought some refrigerator magnets and not much more. At this point I was still thinking I didn’t want to get too many t-shirts, because I had very limited carrying space. Eventually, I gave up on that, as I was able to pack more and more efficiently with every move. But really, this isn’t very important, is it? Let’s get on with it, shall we?

It was in fact dark by 8:30 p.m. when I emerged on the roof. The sky was clear and full of light pollution from the remarkable lights of Los Angeles. The city (at least its downtown) is like a lonely mountain in the middle of plain. Just a flat grid of lights all leading to a central peak of skyscrapers. It is kind of pretty, but of course it blots out all but the brightest stars and planets. The line for viewing through the 12″ Zeiss refractor was long enough but not depressingly so. I fell in, and it took about 20 minutes. As I mentioned above in my journal entry, I got to talking with a science teacher from India named Gita who was ahead of me in line. It took me quite a while to realize she was from India, because she had virtually no discernible accent. I don’t remember much of what we talked about, except that she was well versed in earth sciences but had never seen a planet through a telescope. I remember being eager to engage and encourage her about astronomy, and also feeling somewhat rebuffed. I wish I’d written more down at the time. Otherwise, there were quite a lot of people in line or milling about on the roof. It was a very pleasant night weather-wise, and there was a pleasant atmosphere among the museum patrons, with lots of lighthearted banter and the murmur of many energetic conversations going on at once.

The target for the evening was Saturn, which was high in the southern sky. Venus and Jupiter were low in the west and close to setting if not already set by 8:30. Mars was rising over the city. As you may recall, it was near its close approach but had been covered by a global dust storm since the end of spring. That left Saturn as the best candidate, and let’s face it, Saturn is always a good candidate. The line made its way into the observatory dome and wrapped around and up a narrow wooden staircase to the eyepiece. Staff were stationed here and there to direct and assist, and while I seem to remember someone being at the top of the steps, my pictures show that wasn’t the case. Huh. Anyway, one would go up to the eyepiece, get in a good look, then come back down and head to the exit, and then the next person would go.

The Zeiss 12″ refractor, looking as much like an antiaircraft gun or laser turret as weapon of scientific inquiry.

The Zeiss refractor is a 12″ diameter tube, about 16 feet long (f/16, I guess). It has a variety of other scopes mounted with it for guiding, spotting, and additional views, whatnot. The whole lot is on an equatorial fork mount, kind of. As noted above, the view of Saturn was, well, standard and adequate. Since Yerkes I had been tempering my expectations, and what would one expect of heavily light-polluted skies over a major metropolis? So, the seeing wasn’t great, kind of wavy. The magnification was 175x, which I can often beat at home. On the other hand, it is a 12″ refractor, so lots of photons to look at, which makes for a brighter image, which probably counters the light pollution some. Plus, it’s the Griffith Observatory Zeiss refractor, which is said to have had more humans look through it than any other telescope in the world. That makes it worth being on my list.

After admiring the view of Saturn for a minute or so and then the view of Los Angeles for a while, I decided to call it a night. I made my way to the parking lot and called for a Lyft, which was also true of about a few hundred of my close Griffith friends, or so it seemed. Anyway, it was pretty crowded. While I waited for my ride, I could hear the sounds of baseball from the valley below, which was I guess coming from Dodgers Stadium, about 5 miles away. It sounded like it was just over the hill from me. My Lyft driver had to make a couple passes, as I didn’t see him on the first one. We eventually connected, though, and had a quiet ride back to my abode, as he was pretty much the opposite of the driver I had on the way to Griffith. Well, it takes all kinds.


My trip to Griffith was a delight. I thoroughly enjoyed the blend of old and new, nostalgia and innovation on display there, as well as just soaking up the astronomical goodness of it all. I was very pleased to see how many people, and particularly adults, were there, not just for the displays but for the nighttime observing, on a Wednesday. Although I hadn’t been familiar with Griffith before, I am really glad I put it on my list and that I got to look through their historic Zeiss refractor. With the possible exception of those hot dogs for dinner, it was a wonderful experience.

A pleasant Sunday night. I pondered long about going out, because, much as I love the NexStar 8, it is a pain to drag it down to the pool deck. I finally discerned that my 3 targets – Jupiter, Moon, and Saturn – would be visible from the deck, so I set up in the northwest corner there. The problems were shakiness (really need to reinforce the deck at some point) and the TV aerial, which turned out to be right in the path of the moon and Saturn. The moon was just a few degrees W of Saturn, both sitting just above the Teapot of Sagittarius. Jupiter was 15º or so to the west just above Antares in Scorpius/Ophiuchus.


Southern region of the Moon. North is up. Just inside the terminator on the right (West) from bottom to top you can see Schiller, Gassendi, and Kepler, mentioned in the writeup.

I started with the Moon, using 32 mm = 62.5 X with moon filter and variations with 15 mm, 9 mm, and 2x Barlow. I don’t know the moon that well, so didn’t do much more than identify several craters. In the SW quadrant; Schiller, , a long, squashed crater; Gassendi was just east of the terminator – large with prominent central peak; small Flamsteed; up to Encke and Kepler, just on the terminator. On into the NW, Prinz on the terminator, and I think it was breaking dawn on Aristarchus, which sounds like a new age album. Saw Bianchini and Sharp just outside Sinus Iridum. After that I made my way to Mare Tranquillitatis to see if I could find the Apollo 11 astronaut craters: three small craters in a row just north of the landing site and named Aldrin, Collins, and Armstrong. Turns out they are quite small. While theoretically in reach of my scope, I had two problems (at least): 1) I had neglected to add my dew shield and was starting to fog over, and 2) the aforementioned TV aerial was now sitting across the heart of the moon, so that I wasn’t getting good resolution, even at 222 X. [An article in July 2019 Sky&Telescope suggests a 6″ scope can make them out at 250 X with steady seeing.]


Moved on to Jupiter, sitting low in the SW. Tried pushing the magnification to 333 X, and it was just a bit too much. 222 X wasn’t quite enough, but I didn’t think to use the 15 mm + 2X for 266 X, which might have been Goldilocks. Oh well. The GRS (Great Red Spot) was just past transit, very well placed, but so small! It was fairly obvious but just a tight, dark knot (nought? not.) in the SEB (Southern Equatorial Band), which itself was quite light. The NEB (Northern…) was dark and thick, and some “barges” were visible. The equatorial zone remains heavily shaded, darker than the temperate zones. One northern temperate band was visible. The GRS rotated about 2/3 to the limb while I observed, or so it seems to me as I write this. I tried a variety of color filters, including blue, green, and yellow. The blue highlighted the bands and GRS the best, as one would expect. Green and yellow both gave interesting interpretations but were ultimately not that helpful. Of the Galilean moons, I had just missed Io disappearing in eclipse as it turns out, and also just missed Ganymede emerging from eclipse at the other end of my observations. Oh well. Meanwhile, Europa was about 4 Jupiter diameters from the planet to the west. Callisto was about four Europa-Jupiter distances further to the west. I made a sketch at the eyepiece that shows the distances more or less. The GRS in the sketch is bigger than it appeared.

Moon, redux

Went back to the Moon for a bit after it cleared the tower, as it were. Took another stab at the Apollo 11 craters, but no. Poked around the southern highlands for a bit. I’ve always had a soft spot for Clavius, so I looked there for a bit. Noticed a few clouds moving in and wanted to get some Saturn time in, so moved there.


Even with deteriorating conditions, Saturn looked pretty good. Again, pushing the mag, it was just a bit much at 333 X, so ended up with the 266 X combo I hadn’t thought of earlier. The rings are tilted so that the other edges are about lined up with the edge of the disk. It’s just a bit past opposition (okay, a month past), so there is just a little bit of shadow on the rings right at the pole, or that’s what I’ve gathered. Any way, the rings kind of squish at that point. Not much color tonight, just a yellowish tint. Darker in the N temperate to polar region with a slightly dark band at the bottom. Very 3-D. Cassini Gap easily visible.


I took several handheld pictures and videos with my phone at the eyepiece for all three targets. Moon was best, of course, then Saturn. Jupiter was washed out. Clouds were moving in, and I was tired, so I washed out, too.

Best shot of the Moon for the night. North is right and West is down.
Best of Jupiter for the night, which is not that great. North is upper left, West is to the lower left. More or less.
Saturn. Not as impressive as seeing it live. You sort of see the dips where the rings and the disk limb cross, right? North is right.

Observing from Home – 1 July 2019 – The rest of the story

In my last entry I included my first serious attempts at astrophotography with three pictures of Jupiter. Here, then, are my notes from that night’s observing in general.

  • Jupiter
  • Saturn

  • M8
  • M20
  • M17
  • M22
  • M27
  • NGC 6995


Writing this several days after the fact, so we’ll see how bad my memory is. Of course you won’t know unless I tell you! A good bit of time was spent on the new attempt at technology and astrophotography, which ultimately proved successful, but it took a while. The interface between camera and computer is a bit dodgy at first. No image coming through, even though the cam had power. This may have been an interface issue or that the object in view wasn’t centered enough or large enough or focused enough to produce an image. I eventually added the 2x Barlow, doubling the image size and found Jupiter on the monitor in the preview window of the settings screen. In the actual preview window, though, the image was tiled into 4 images that were raked with horizontal lines. Unplugging and restarting the camera seemed to do the trick, and after only half an hour fiddling, I took my first .mov of Jupiter. It was grainy as hell, but I could sort of see that the GRS (Great Red Spot) was on the limb. Over the next 45 minutes or so I took 8 movies of 50-75 seconds each. I tried one of M4, the globular cluster in Scorpius, but that was just dark frames. This camera is not sensitive enough for faint deep sky objects. It barely noticed Jupiter! Any way, I’ve been processing the movies into pictures with some success. They are grainy, and I have much to learn about processing, but they aren’t bad for a first effort. I thought about recording Saturn, too, but I decided to keep it simple on the first try. I also hoped to see several objects by eye on a rare clear night. So I put the tech away and switched to visual.



I stuck with Jupiter for a good while. It is just past opposition, so it is a great time to observe it. It isn’t very high, sitting on the north side of Scorpius, a few degrees north of M19, about 28º above the horizon according to an app. It’s super bright at -2.6 magnitude. At 62.5x (32 mm) I could see 2 stripes on the disk, on moon to the W (Io), and three to the E. Mostly viewed with the 15 mm and 2x for 266x. It was a pretty stable view. Could make out the GRS easily. The NEB (north equatorial belt) was thick and rusty colored. The SEB was thinner and darker to the … W? of the GRS (toward the direction of rotation). The equatorial zone was orangy and the higher latitudes were lighter. Could occasionally make out another stripe or hints of one above the NEB. I think. Maybe I’m applying that back from my pictures, though.

I tried a couple filters – blue, purple, red, yellow. The purple was a complete washout, making for a big pink blob, and red wasn’t much better. Yellow was okay. Blue was by far the most helpful. That’s when I saw hints of other bands and hints of detail downstream from GRS. This sketch doesn’t look like much, but I watched for a long time with great enjoyment and fascination.

M4 Globular Cluster

I had swung over to M4 before as I mentioned, but went back for more visual. For as big as it is, it’s a challenge. Not to find it but to see it. The surface brightness is pretty low, and I often strain to keep looking at it. Maybe I should have dropped the magnification. I had a hard time making out any detail at all. Just a mess of stars on the verge of vision so as to make my eyes twitch.

M8 Lagoon Nebula

Moved on to several Sagittarius favorites. M8 Lagoon Nebula was beautiful as usual. Not as stand-outish is M42, but up there. Wisps of nebulosity with an X across the center and a swarm of small stars on the east side. At some point in the night I added my sky glow filter – I think much later and then I returned here, I forget – and it really helped bring M8 out from the background.

M20 Triffid Nebula

M20 is hard to compare to M8. Not fair, really. It’s a beautiful thing but so small vs. M8. I think I didn’t use the filter on M20, and it suffered for it. About 1/4 the size of M8 or less. Hints of more complexity maybe and hit of the central star. Should have used higher magnification and the filter. Next time.

M17 Swan Nebula

M17 is always fun to observe. Mostly looked like a checkmark, more than the full swan this night. Not as sharp a line on the swan’t “water line” as often appears.

M22 Globular Cluster

Just a quick look at M22. Enough to say I saw it. I think I was starting to get tired already. Sorry.


Not sure of where it fits in the order now, but somewhere in here I went to Saturn. At fairly low power about 4 moons visible. (… Not sure what power I was using now that I think of it. I really need to start writing this stuff down as I do it.) At 266x it was a little rough but some detail. Still very low in the sky, about 20º above the horizon, so not great detail. Plus, it’s just about at opposition, so almost no shadows. Could generally make out the Cassini Gap, some shading on the planet disk. Rings are crossing in front of the disk. A dark band and gray cap on the top of the disk, but not much color.

M27 Dumbbell Nebula

Turning to the north, Cygnus had risen over the house to about 45º. I slewed to M27, a planetary nebula. It is large enough and bright enough that I wonder if it might appear in the SSSSIV camera. Round, but uneven, brighter on the “sides” than on the “top” and “bottom,” and brighter on one side than the other. It seems to shift as you look at it, though. I used 266x pretty much across the board on everything… I think, and I think I used the sky glow filter? Or maybe I came back to it after I added the filter? Maybe that, because I seem to remember adding the filter on the last target of the evening.

NGC 6995 Veil Nebula

I went to the Crescent Nebula, which isn’t really where I meant to go, which is fine, because I couldn’t see it any way. I chose it from the list of named objects on my paddle control for the C8. What I meant to look at and eventually got to was NGC 6995, the Veil Nebula. It turned out to be the Eastern Veil. This is a pretty bright ribbon of cloud in a long, flowing arc. There are two relatively bright stars nearby and not one bright one in the midst, the signature of the Western Veil. It has a few kinks and bulbs, as it were, and is quite an interesting object. Regrettably, I was definitely getting tired and didn’t give it the attention it deserves. It definitely benefitted from the sky glow filter.

I revisited a few previous targets, but as I said, I was getting tired. Plus more clouds were moving in. Plus the dew was getting heavy. In fact, I noticed as I was packing up that the scope’s corrector plate was starting to dew over. On the whole, a good night.

I’ve really been wanting to see Jupiter lately as the GRS is “flaking” and doing weird stuff and shrinking. It’s been months since we’ve had decent night weather when I was free, but tonight was good. Well, clear. The seeing was crap. Any way, I debated going out at all because it’s a pain to take the scope down to the pool, and the deck is full of plants for the garden. I hit on the idea of setting up in the front yard. At 11 p.m. this would give me about an hour on Jupiter before it hit a tree, so to speak. Lots of trees in the front yard. So, that’s what I did!

Quick sketch of Jupiter, ex post facto

Did I mention the seeing was lousy? I could watch the waves of atmosphere rolling over the face of Jupiter. So it was mostly fuzzy and indistinct, even though I was well below the useful minimum magnification for planetary detail. I started at 62.5 X (32mm) and could identify 3 moons (Io was occulted, and I had just missed its disappearance) and the NEB and the SEB. As I’ve seen in pictures lately, the equatorial zone is relatively dark with a tan color. I have to admit I still get confused about image orientation. I think, from pictures, that S was up, but it should have been corrected by the diagonal. But when I pushed the scope toward the N, north was at the bottom. It doesn’t help that I had turned the diagonal to about 4:00 so I could sit and observe. I think that changes the orientation. Well, let’s say S is up. In watching for about an hour with increasing magnification (133, 227, 266, 444) I could see the NEB was thicker and darker, and I thought I could see some gray blocks along the SEB. The polar regions were quite washed out. The GRS was on the flip side, I think. It may have been just on this side about to roll over, but I couldn’t make it out if it was.

I did manage a few pictures holding my phone up to the eyepiece at 133 X and 444 X. Higher power was better for those.

I processed a bunch of pics into this one image using GIMP and Preview. Not very high tech, but it is my first attempt at planetary image processing. I’m pretty sure I didn’t do it right.

Flaring Satellite

While I was looking at Jupiter I saw a flash out of the corner of my eye. I thought maybe someone turned on a light in the house and it caught in my glasses. Then a few moments later, there was another flash. I looked away from the eyepiece. I was facing north. A third flash, and I found it just to the right of the “handle” of the Little Dipper, Ursa Minor. As I watched, this object, which I surmised to be a tumbling satellite, flared at least a dozen times as it moved from NW to NE until it went behind some trees. The flares varied in intensity from … I’m going to guess magnitude 1 to -4 or more! (The smaller the number the brighter the object, and each magnitude is a factor of about 2.5). That brightest flare got me to exclaim, “Holy moley!” out loud. It was just a few seconds between flares, and the difference in brightness wasn’t uniform, which is why I think it was tumbling rather than just rotating. Any way, this was very cool. I also noticed how clear the sky was, as I could see all the stars in the Little Dipper.

M104 – The Sombrero Galaxy

Quick sketch of M104 ex post facto.
That’s a star on the left, not just a random dot.

Once Jupiter got into the tree, I went looking for galaxies. My observing spot was not ideal, as I’d be looking just over the house, which can produce heat issues, with some lights on in the bedrooms, but it turned out okay. I used 62.5 X and 133 X mostly. M104 is a longtime favorite and was still just visible from my position. It never appears very large or much at all like the pictures, but I like it anyhow. Sitting next to a 6.5 magnitude star (going by the Pocket Sky Atlas), it was more radiant than I remember seeing it before. Still best seen with averted vision, there is a bright core – really quite bright tonight – surrounded by nebulosity, but it did appear to have rays of light shining to the … I don’t know.. South? I’m not sure how to explain this. Perhaps a defect in my eyes or optics, although nothing else gave this effect over the night’s observations. Maybe it’s just a really, really bright core, seen on a really clear night. Having spent a long time on fuzzy Jupiter, you might think I’d spend more time on this beauty, but I kind of said, “Oh, that’s pretty,” and moved on. Having added a sketch in my notes, I thought that I had drawn something like it before. Looked through my previous journal entries and sure enough, on 1 May 2013 I have a very similar sketch. The rays aren’t as pronounced, but they are implied (or at least inferred). That was with the Meade ETX90, so more than doubling the aperture perhaps makes a difference.

Virgo Cluster Galaxies

I moved on to a couple of the Virgo Cluster galaxies, starting with M58, because that’s one of the numbers I remember being there. Here my weaknesses as an observer really start to show up. First, I was not prepared. I didn’t have a plan for what I was going to look at and had done no research. This is greatly enabled by having a GOTO scope. Second, I have no patience. (This is an obvious lie, as I just spent an hour looking at fuzz ball Jupiter, but what I mean is….) I don’t take time to soak in the details of what I’m looking at. Well, often that is the case. Third, I don’t know the basics of observing, like image orientation in the eyepiece, angular size of objects and how to estimate them, visual magnitudes of objects and how to estimate them, stuff like that. None of this means I can’t enjoy my observing. It just would be more… insightful if I knew what I was doing, and I’d feel more confident. Any way….

M58 is a fairly large, diffuse, fuzzy object. I didn’t notice any bright core, but I didn’t really study it very long. I would say it appeared larger than M104 and not nearly as distinct. There was a star nearby both of them, though.

I followed an urge to move on to M60, which I knew to be close at hand, although it turns out to be in the opposite direction from what I thought. Hard to tell with the GOTO, which jumps away and slews back slowly rather than just gliding a few arcminutes over. M60 has much the same appearance as M58 – big, fuzzy patch with no noticeable core. I scanned around the area a bit, thinking I’d find M58, and I did find another galaxy, but the neighbor star was missing. Upon review, I think this was M59, another elliptical galaxy that lies between M60 and M58. I hadn’t even brought my sky atlas outside, so I had no idea what the layout was. Rather than going to get it, I abandoned Virgo until another night. This was also partly informed by it getting late and cold, but I wasn’t quite done yet.

(I later found my journal entry for 11 March 2019, the last time I was out with the scope, with a similar entry for M58-59-60. Maybe someday if I do it often enough, I’ll learn and remember.)

M51 – The Whirlpool Galaxy

Ex post facto sketch of M51. There’s a star in the upper right, and another in the disk of the galaxy. This second was actually not as bright as the first, although it looks the other way around.

I thought I’d end on a high note, literally and figuratively, turning my scope upward to another favorite, M51, the Whirlpool, the large face-on spiral galaxy and its companion. This was the best I’ve seen it since Mayhill, NM, in the 25″ Dobsonian in 2010. Two fairly large, bright, distinct objects of comparable size at first. As I’m writing two days hence, I forget exactly what eyepiece I was using, but I think I started with the 32mm and pressed to the 15mm for 133X. Any way, as I looked, the larger spiral, which was fairly vague, began to reveal itself. It remained pretty ephemeral, but it seemed to show indications of its structure. The whole was quite beautiful. I kept getting glimpses of a star in the bounds of the spiral playing peekaboo with me. Definitely the best object of the night. Again, though, the orientation has me baffled, to the point that, upon reflection, it is possible I have sketched the reverse of what I was actually seeing. It may be that the larger spiral galaxy should be on the right and the companion to the left.

What is reality?

Saturn, Sort Of, and Out

By this time, Saturn had risen high enough to be seen. So I took a look. It suffered from the same poor seeing and thick atmosphere as Jupiter. No detail at all – no color, no shadows, no Cassini Division in the rings, no nuthin’. I should have left well enough alone and quit on M51.

The night had grown cold, and I with it, so I packed up. Not a bad night on the lawn.

Observing from Home – October 1, 2018

I let three good, warm, clear nights slip by me this weekend. Each night right around sundown, the clouds made a strong appearance, so I occupied myself with other trivial endeavors rather than haul out the astro gear. Later in the evening, each evening, as I took a look outside I found the skies to be clear and inviting, but it was too late to set up. There was also a lot of moon on a couple of those nights, but still. So having missed three good chances to get out under the sky, I was determined for last night. Consequently, I was convinced the clouds would close in. That’s the usual pattern. But I lucked out or was given grace, depending on your theology, and the sky remained clear.

I set up the Celestron Nexstar Evolution 8″ on the pool patio. It’s the first time I’ve had it out since Green Bank in July, so it took some work remembering how to get it all put together right and to attach a few doodads that had been taken off for travel. I got it set up as the stars were coming out, so I was able to get it aligned. Then I got the call in for supper (we eat late around here), so I parked it and went to eat. I got back out at about 8:35, and the sky was still clear! Amazing! Also, it was warm enough that a long sleeve shirt was all I needed for my whole time out. That and my Palomar beanie.

What I saw:


My primary targets were the planets, especially Mars. I spent a good bit of time bouncing back and forth between Mars, half way up the SE sky, and Saturn getting low in the SSW. More on them in a minute. From there, a quick circuit of the summer glories near Sagittarius, then on to the ice giants, Neptune and Uranus. After that, Andromeda seemed the logical next target. Then, I employed the “Sky Tour” feature of my telescope, letting it suggest nearby goodies. This was cool, because otherwise I might never have seen a couple of these, and I didn’t have a plan, either. I finished the night with three favorite targets around the Summer Triangle, which was still about half way up in the western sky. As I started packing up the gear, a very bright, green fireball crossed the sky in the SW, lasting a couple seconds! Great way to end the night! I was out from 8:30 – 11:45 p.m. EDT.


Weather: Warm! in the upper 60s, maybe over 70. Humid. No wind to speak of. No moon until after midnight (@20 days old).

Seeing: 4/10 – pretty wobbly, based on [magnification/in. aperture]

Transparency: 5/10 – high humidity, maybe a thin layer of cloud even



I’ve been waiting to see Mars all summer. As it was heading for its nearest approach in July, it was blanketed by a global dust storm that obscured any surface markings. I did get a chance to see it at the Lowell Observatory in Flagstaff, AZ, in August, and the dust was starting to settle. Some markings were present to the patient observer at that point. As for this night, the seeing was pretty poor and the transparency didn’t help, but I managed to push the magnification to 222x with the 9mm Plossl eyepiece. That’s well below the minimum to resolve much (312x for 8″ aperture), but I was able to discern some surface markings in the better moments. According to Sky&Telescope (S&T), the disk was 16″ (arcseconds). There was a band of darkness along the northern hemisphere, and it seemed to double back on itself about halfway along the equator. What was more striking was that the disk was only 89% illuminated (according to S&T) and showed as a gibbous section, like the moon a couple days after full. That doesn’t happen very often with the outer planets, but there it was. There was a slight hint of the southern polar ice cap, but I wouldn’t say I really saw it.

I tried a few different filters with varying results. Red definitely made the dark area stand out more, but it overwhelmed anything else. The yellow filter did almost as much to increase the surface contrast without being as overbearing. Blue should have helped bring out the polar cap, but it seemed just to wash everything out. Just not good enough conditions for much detail.


I went back and forth several times between Mars and Saturn for comparison and because Saturn was heading for the trees, but I wanted to see if there was any movement on the surface features of Mars. Any way, Saturn looked a great as the conditions would allow, which is to say, “meh.” Saturn’s disk was about the same size as Mars, but that’s not counting the rings. Using the same 222x magnification as on Mars, I couldn’t really make out the Cassini division in the rings, as the outer ring appeared unusually dark. I attribute this to the poor transparency. With patience, I could see some shadow on the rings near the eastern limb in the rear and some darkening around the north pole. The disk is covering much but not all of the rings. Usually I can make out some color differences on the disk, but there wasn’t much to be seen this night.

The red and blue filters didn’t do much for Saturn other than make the outer ring almost completely invisible. The yellow filter helped with the contrast a little bit, making the shadow effects more noticeable but not much more.

I’ve seen Saturn this summer in my scope, the Yerkes 40″ Clark refractor, the Lowell 24″ Clark refractor, and the Griffith Zeiss 12″ refractor. This night ranked somewhere in the lower half, although my scope at Green Bank ranked near the top. Conditions make a huge impact, regardless of how awesome the equipment. Of course, my 8″ is 80 years newer than the newest of the rest in the list.


The Trifid forgot to show up for work tonight. It’s fairly faint to start with and the poor transparency made it essentially invisible. I know I was on it because of the two stars that sit in its midst.


The Lagoon is always a pleasure with its large open cluster and broad nebulosity. I’ve noticed that the Nexstar doesn’t pick up the nebulosity as much as my Newts, and again, with the poor transparency, only the brightest areas were clearly visible. I admit I didn’t study the view for very long, as I had other things in mind. I think a nebula filter might be a worthwhile investment, though.


The great Sagittarius globular cluster is a real showpiece. It stands up to a good bit of magnification. At 222x the stars were resolving in a layer across the surface, although the underlying multitude were less forthcoming. The cluster filled most of the field of view with dozens of brighter stars in that top layer. The whole this is sort of tick-shaped, but apart from that, it’s a beauty.


I’ve been tracking Neptune for about 10 years. By tracking, I mean I try to find it every year or two when it’s in a favorable place. Well, now is the season. Back in 2008 it was near the point of Capricornus and easily visible in binoculars. It has made its way into easter Aquarius, between Lambda and Phi, and I had a hard time knowing which object was the planet. Part of the problem is my tracking was off a bit because of parking the scope during dinner, but Neptune is also really small (S&T: 2.4″) and faint now. I finally found it, I think. At 333x magnification it showed itself to be a slightly nonstellar disk, just barely. I’ll have to go back and try it again.


Same thing with Uranus. That is, I’ve been following it for as long as Neptune, and it’s harder to find than it was when I started. It has traveled from under the Circlet of Pisces to just east of o Piscium moving into Aries. Uranus is an easier find than Neptune, being 3.7″ (S&T). It was clearly nonstellar and a very small disk at 333x. I might even have seen a little bit of color? A hint of blue maybe? Maybe.

M31, 32, 110

The Great Andromeda Galaxy is always a treat. Enormous and bright, it extends past the field of view in my 40mm e.p. at 50x, so it’s over a degree (twice a full moon). The conditions cut it down some, but it’s still huge. The western edge has a dark dust lane running along it, so it’s more defined than the eastern. (I think I have my directions right). There is a bright, small core surrounded by this extended “nebulosity” that is a 100 million suns. Other than the hard edge I didn’t notice much structure.

M32 is an elliptical galaxy just off the side of the M31. It’s tiny by comparison, but still pretty good size as visible galaxies go. It has a bright core surrounded by an oval of rich haze. It didn’t appear to be over or in M31 but pretty close.

M110 is another elliptical galaxy to the NW of M31. It appears larger than M32 but looks similar with bright core and surrounding oval. It’s edges don’t look as well defined as M32. It is very impressive as compared with other Messier galaxies, just small compared to M31.


The Triangulum or Pinwheel Galaxy is a large, face-on spiral, but tonight it looked like a large, faint fuzz. I’ve found it easily in binoculars many nights and occasionally seen it naked eye (maybe?), but the conditions were not favorable this time, and it didn’t have much to offer. Hey, we all have off days.

Eta Cassiopeiae

This was the first of the items suggested by my telescope’s computer that I looked at. It’s a double star with two yellow white stars, one significantly brighter than the other. I haven’t done much with double stars, but this was pretty to look at.


Scope called this the Triangle Cluster, I think. It’s an open cluster with several brighter stars that make up an isosceles or maybe right triangle with fainter stars laced back and forth across it. I’m not a huge fan of open clusters, but this one is pretty interesting.


This is allegedly a face-on spiral galaxy. I’ll believe it when I see it. It wasn’t a good night for galaxies, or at least for the faint ones. I can’t swear that I even identified this. There was a ghost in the field of view, just kind of a faint slash, that moved with the field, so I guess that was it.


Another of those open clusters I don’t care much for, except I spent a long time on this one. If I were going to name it, I’d call it the Atlas Cluster. I imagined a bulky figure standing with arms stretching out and up (toward NW I think), legs locked, and a globe on its back. It started with two close stars that serve as eyes and three down the middle for abs. Strands running up and out in curves that define the limbs. It’s a sizable cluster with a couple dozen brighter components shaping the titan character and dimmer stars surrounding for the globe and environment. I enjoyed it!

Double Cluster

This pair of open clusters leaning against each other between Cassiopeia and Perseus are beautiful in binoculars. You need a pretty wide field of view to take it all in. Even with the 40mm e.p. I could only fit about one and a half of them at a time. Dozens and dozens of stars, mostly bright white or blue with one or two red ones toward the middle of the two.

Kite Cluster

Described as a diamond of stars with a string of five or more for a tail. I think I saw it, now that I’ve seen pictures of it, but it didn’t look like a kite to me.


This planetary nebula (poorly named, having nothing to do with planets other than sort of looking like one) is fairly compact, maybe 15″? and appears kind of pine tree shaped, so it’s doubly badly named as Little Dumbbell. Maybe with better conditions and/or more patience it looks like the Dumbbell. I think I saw mostly the core. It varied in consistency from top to bottom, being kind of patchy. It sits next to one or two field stars to the west.

Gamma Andromeda (Almaach)

This is a beautiful double star out on the tip of Andromeda with the two stars varying in magnitude and color. The brighter partner is several orders of magnitude brighter than the fainter companion. The brighter is a golden yellow tone, while the partner is a bright blue. Very pleasing pairing.


The Dumbbell (planetary) Nebula appears vastly larger than the Little Dumbbell! A large round object with mottled appearance, M27 filled about half the field of view at 222x.  It’s an easy target and impressive to look at. Imagine, that’s what our sun may look like in 5 billion years.


Unless it looks like this. The Ring and the Dumbbell are both remnants of sun-like stars. It’s thought that they appear at 90-degrees rotation to us, so that we are looking at the side of M27 and down the throat of M57. The Ring is farther away and appears smaller. Nevertheless, at 222x it was clearly a ring of nebulosity. I didn’t see anything in the middle, although sometimes material or a star can be seen.

Epsilon Lyrae

The Double Double is a pair of binary stars that orbit each other. With binocs you can split the one star into two, and at 222x the two split into pairs. The two pairs run perpendicular to each other, so that one pair appears up and down while the other appears side to side. Very cool, and a good end point for the night.


While I was starting to tear down, a bright green light lit up the sky, casting reflections from the telescope tripod legs and shadows on the ground. I looked up to see the end of the fireball, a very bright meteor. It was bright green. A remnant tail about a degree wide and 15 degrees long stretched from the endpoint up the sky. It seems to have run a track that appeared almost straight up and down, maybe from Delphinus down past Altair through Aquila, ending about 15 degrees above the horizon. The tail faded out quickly.

In the end…

Although the conditions weren’t ideal, it was still a very fruitful night out under the sky, which always does my heart and soul good. So glory to God who set all things in their courses and gave some of us eyes to see and souls to thrill at the beauty of it all.
