Observatory 7: Kitt Peak, Part 1

Okay, right off the bat, you can see my annotated pictures of Kitt Peak >here.<

I am now writing this in March, so –– Good Lord, it’s more than six months since I was there??!!! I didn’t write much in my journal at the time, or here. Fortunately, I did add some commentary to the pictures linked above. Well, let’s see how much I remember.

The National Optical Astronomy Observatory at Kitt Peak is about an hour’s drive and change west of Tucson. They run three tours through the day most days: the solar observatory, the 2.1 meter, and the 4 meter. They open at 9:00 a.m. and tours start at 10:00. It was my intention to get there for the tours, because that was sort of the point of being in Arizona, so I was up and out by about 8, which is pretty good for me. Had breakfast from McD’s in the car, which was about the worst food I had on the whole trip — except for breakfast on the Capital Limited. After driving about an hour on that beautiful morning, I was starting to see some mountainous terrain pop up, and not much later started thinking I was seeing a shiny white or silver dot on top of one of the mountains. As I got closer I became convinced it was a dome. Sure enough, I soon came upon the turn off to Kitt Peak! I was very excited. The road up the mountain was quite a drive, a bit of a white-knuckler in places with some pretty serious switchbacks and sheer drop offs. Nevertheless, I made it safely to the top.

One of the first things I noticed when I got out of the car in the parking lot was that it was very, very quiet, except for some wind in the trees. I liked that. Which is good, because I spent all day and a good bit of the night there. Well, about twelve hours or so. I made my way to the visitors center, which is a small brick building with a beautiful mural, a fair sized patio with some tables and benches and sciency things, and an observatory dome on the roof of the building. Inside, it is filled with sciency displays in about 2/3 of the space and a gift shop in the remaining 1/3. Went to the counter and paid for the three tours ($15 for the lot) and for the evening observing program ($75). There were two choices for observing, a general objects and deep sky program and “Our Marvelous Moon.” It still being the monsoon season, I had reserved a spot for the moon program as I figured you can see the moon pretty well even in pretty bad conditions, but you can’t see all the faint fuzzies unless it’s pretty good.

Tour #1

The first tour was led by docent Katy, who is a professional astronomer, retired with 50 years experience. She was very knowledgeable as you might expect, and very engaging, as you might not expect. About 15 people had appeared for the tour, which began in the center with a little history about how the site was chosen, negotiated with the Tohono O’odham Nation, and developed as the National Observatory. The object of the tour was the McMath-Pierce Solar Telescope, which had been retired earlier in the year. It is fascinating design and an exceedingly large instrument. As you can see in the pictures, there is a large vertical column connecting with a diagonal structure that extends underground. This diagonal column is north >polar aligned<, that is, it is aimed at the north celestial pole, the point to which the earth’s rotational axis points in the northern sky, like an equatorial telescope mount. Because it is, sort of. Turns out there is a rotating flat mirror at the top of the structure on the diagonal axis, and it tracks the sun. The sunlight reflects off the mirror and down the axis through a 500 foot optical tunnel to a concave secondary mirror, then back half way up the tunnel to any or all of three more mirrors. These mirrors reflect the light down into a variety of spectrograph instruments in a subterranean laboratory (which sounds more evil than it is). We got to look in from an observation room about half way down the optical tube, which looks kind of like a subway station. We also got to go down to the lab, although since it is closed now we could only look in. They did 5 or 6 decades of groundbreaking solar science there, but now it is considered obsolete. So we’re back to the question of what do you do with giant, historic, obsolete astronomy equipment? Oh, fun fact. While we were walking around the solar observatory, half the sky was clear blue and the other half was entirely socked in and producing lightning and thunder, so that was kind of exciting. What happened to that beautiful morning I drove in on?

Tour #2

We made our way back to the visitor center to see if there was anyone new going on the next tour. I don’t remember now if there was or not, actually. Katy led the second tour, too, which was to the creatively named >2.1 Meter Telescope< (that’s about 84″ or 7 feet). It is a large Cassegrain-style reflector on a large, equatorial fork mount. That it is equatorially mounted means the base is at a 32º angle from vertical. As the mirror alone weighs a ton and a half, having this enormously heavy yet super-sensitive piece of equipment standing at NOT perpendicular to its base felt a bit unsettling, like something was not right. Like the angles! (See what I did there?) Any way, this telescope has done lots of groundbreaking science and is particularly notable for being the first scope to use >adaptive optics<. At this point, several months after the fact, I don’t remember why, but I felt oddly bored with this telescope. Maybe it was that Katy spent a good bit of time explaining adaptive optics, with which I was already familiar. I remember being grumpy about that guy in the group who thought he knew more than the PhD astronomer, so maybe I converted my anger to boredom. Maybe I was hungry. I don’t know. Looking back, it’s an impressive instrument that I’d love to have in my back yard.


We returned to the visitor center, and those of us who were staying on (pretty much everyone) could have lunch if we’d brought it, which it says to do in the literature for the tours. There is no food service for visitors. So I had brought some leftovers from dinner the night before at Za’atar, a mediterranean restaurant in Tucson. The weather was stable and pleasant at that point, so we ate out on the plaza. There are a couple of tables and benches, along with a couple cool sundials that have no practical application to lunch. I sat with the woman who manages the gift shop and schedules people for tours and night programs. She was very interesting to talk with. She is a member of the Tohono Nation and active in her church. She told me that she loves the quiet and the peacefulness at the top of the mountain (me, too!), and that people in her church ask her to pray for them while she is at work because she will be closer to God. We were both a little disappointed in their theology, but she prays for them nevertheless. She told me about her family and some of their struggles, so through the rest of my travels I prayed for her. 

Meanwhile the weather began to deteriorate, with clouds and fog moving in across the valley and across the mountain, too. Great. Made for some interesting photos, any way.

Tour #3a

The third tour was to the Mayall 4.1 meter telescope, the largest on the mountain. This part was led by a different docent, named Dave if I remember correctly. We began with some background and history at the visitor center, then moved to the parking lot. Two reasons for that: first, we were driving to the Mayall dome, and second, in the parking lot is a large cement donut with a mural painted on it. I had noticed it on my way in but not really looked at it. It turns out that the donut is a slug the same size and weight as the mirror for the 4.1 meter telescope that was used to balance the scope during construction. Once everything was finished and nothing was likely to fall, then they put in the actual mirror. Once that was done, they had to figure out what to do with a giant cement donut. Rather than roll it down the mountain, they invited a Tohono O’odham artist to do a mural on it, and it was put on display in the parking lot as you walk toward the visitor center. It’s pretty cool on all counts. Dave pointed out that a 160″ disk of glass weighs a couple tons, or at least this one does. What is remarkable is that the aluminum coating on the glass disk that makes astronomy possible is equivalent to about two paper clips, just a few molecules thick. Amazing!

We all loaded in a big white van to head up to the Mayall dome. We hadn’t gotten a quarter mile down the road when someone raced up, flagged us down, and told us we couldn’t go, because it was a hardhat day. They were renovating the dome and moving stuff with cranes, so it was declared unsafe for visitors. Well, that made for a short tour. We ended up back on the patio, and Dave continued his lecture valiantly. Shortly, though, Katy showed up, talked with Dave for a minute, and then excitedly told us they had arranged to let us see one of the other telescopes, the WIYN 3.5 meter.

Tour #3b

WIYN stands for Wisconsin, Indiana, and Yale Universities, and the National Optical Astronomy Observatory (NOAO, i.e. Kitt Peak). The WIYN scope, a large (obviously) alt-az-mounted Cassegrain reflector, is generally not open for public tours, but it was also down for maintenance, so we got lucky. It is about 20 years newer than the 4.1, and consequently it is vastly lighter and more compact and housed in a much more efficient box with shutters instead of a classic dome. Because the mirror was spin cast and honeycombed, it weighs about 1/8 of what the 4.1 meter mirror does. This means the mount can be correspondingly smaller and lighter, and the whole thing is just a lot easier to deal with. It has capacity for detector instruments in three different places at once that can be switched between easily by, well, I guess throwing a switch to move the tertiary mirror. There are dozens and dozens of actuators on the back of the primary mirror, which are not so much for adaptive optics as to correct for stresses when the mirror is tipped at different angles. Engineer Emily gave us the tour. She has been working on this scope since she was an undergrad, and now she’s the managing engineer for it and probably not yet 30 years old.

That concluded the daytime program, three and a half telescope tours for $15. Not a bad deal. I spent quite a while browsing the swag in the gift shop and exploring the displays in the visitor center before the next part of the adventure began.

Sabbatical 2018: The Movie

Here’s a video summary of my sabbatical travels touring U.S. astronomical observatories. It is entirely inadequate to capture the depth and richness of the experience, but it will give you a taste with some pretty pictures and peppy music (from http://www.bensound.com).

The review presentation

I presented this with a review of the whole experience, or bits and pieces of the whole experience, for the congregation after worship on Sunday, December 9, 2018. We also video recorded that presentation, including this. It’s under an hour long, and you can see that here:

A Sabbatical Map

Here is a map of my sabbatical journeys. It includes the trip to Green Bank, the New England swing, and the Grand Tour in chunks. The paths are approximate, especially on the Grand Tour, as they are here driving routes, and I took the train. Also, I didn’t put the exact addresses of the places I stayed. But you’ll get the idea. I think if you click on the box in the top left of the map header you’ll get the legend. Then if you want, you can turn off the driving routes, which will make it easier to see the places I visited. There are several light blue pins marking places I thought I might get to but ended up not going. This time. I worked out a rough estimate that I traveled over 8000 miles in a little over two months.

I can’t tell you how grateful I am for this experience, for the opportunity to travel to see these amazing astronomical instruments, and for the people who made it possible, namely my congregation at Catoctin Presbyterian Church, my family, and my wife Molly. I am grateful to the church for the financial means to go and for the spiritual support to send me. I am grateful to Molly for her encouragement and for her taking over many of the duties I left as I went. I am grateful to God for the privilege of this journey and for these beloved people in my life.

As my sabbatical is drawing to an end I plan still to keep writing about my experiences. I’m still processing the whole thing, what happened, what didn’t happen, what I learned and didn’t learn, what it all means. So stay tuned.


Photo Dump… Observatories 7-17!

My sabbatical is drawing quickly to an end. My Grand Tour wrapped up last week. My writing output has been lousy. I do, however, have lots and lots of pictures from the Tour that are in annotated albums over at my Google account. (My last photo dump went to my flickr account, but I got a new Android phone for the Grand Tour, so all the pictures automatically synced with Google, so there we go.) So I’m doing what I did after the Lesser Tour and dumping the pics for you to see. I then hope to go back and add commentary posts here for each leg, plus some interpretive and reflective posts on the whole experience.

So here we go. Click on the headings to see the pictures.


Kitt Peak Observatory

Kitt Peak, near Tucson, Arizona, is the National Optical Astronomy Observatory for the United States, established in 1958. There are over two dozen telescopes of various shapes, designs, and age there ranging from 16″ to 4 meters (160″) in size. They do a nice job with their tours, visitor center, and gift shop. I also participated in a nighttime observing program, and that was also well done, despite the monsoon making actual observing impossible.

Sunset at Kitt Peak

As part of the evening program, we got to view the sunset from the crest, which was spectacular. I took many pictures which only hint at the glory. The clouds made it more dramatic, but as the light faded the clouds took control of the night, precluding any astronomical observing.

Mount Graham International Observatories

A couple hours east of Tucson you can find Mount Graham, but you can’t go up it without a permit or signing on with the Eastern Arizona College Discovery Park tour, which is what I did. It takes over an hour to ascend the mountain road with its 108 switchbacks. At the summit are three observatories: the Sub-millimeter Radio Telescope, the Vatican Advanced Technology Telescope, and the Large Binocular Telescope. We toured all three. Meanwhile, the weather degraded from mostly sunny to socked in, foggy, and 25-30 mph winds. The monsoon is real. I’m sure it had nothing to do with me being there.

Lowell Observatory

I traveled by car from Tucson to Flagstaff to see the Lowell Observatory, about a 4-hour drive. It saved me some logistical nightmares of getting there by train. Lowell is a beautiful facility, and they do very nice interpretive work. They also do public observing every clear night, and we happened to get such a thing while I was there. Lowell, named for famed astronomer Percival Lowell, is where Clyde Thombaugh discovered Pluto.


California Science Center

Not an observatory, but a cool science museum that has lots of space artifacts including the space shuttle Endeavor.

Griffith Observatory

Sitting on a hill overlooking Los Angeles is Griffith Observatory, named for Griffith Griffith. Yep, that was his name. This facility has been an important center for science education in L.A. for generations. It’s still very cool. They do public observing through their 12-inch Zeiss every clear night, despite the atrocious light pollution. You still get a decent view of the planets, which can be a real Gee-Whiz! moment, especially for the uninitiated.

Palomar Observatory

The Big Eye, that is the 200″ Hale reflector, one of the most famous telescopes in the world, is housed in this beautiful, Art Deco observatory dome. If you ever see an observatory in a cartoon, it’s probably based on Palomar. It is still among the largest telescopes in active service, and this is an active scientific facility. A couple hours southeast of Los Angeles, actually closer to San Diego, Palomar doesn’t suffer too much from pollution of the bright lights, big city. They have nice gift shop and visitor center and a good tour.

Mount Wilson Observatory

Mount Wilson was one of the first great observatories on the West Coast, developed by George Hale, the man behind Yerkes and (eventually) Palomar. It’s about an hour and change northeast of Los Angeles and is home to several former claimants of World’s Largest Telescope. Now primarily an educational outreach facility and center for outdoor activities like hiking and mountain biking, Mt. Wilson played a key roll in changing the way we understand the shape, structure, size, and age of the Universe.

New Mexico

Molly flew out to join me in Albuquerque 32 days after I boarded the train in Harpers Ferry. We spent a day doing a self-guided Breaking Bad tour, which you can look here at if you’re into the show. We also enjoyed the New Mexico Space History Museum, the White Sands National Monument, the Three Rivers Petroglyph park, and the Valley of Fires lava flow site. Again, if you are interested in these, feel free to click on over. I’m going to keep the major bullet points for the official Grand Tour sites, such as…

Sunspot and Apache Point Observatories

Up on a mountain overlooking Alamogordo and White Sands, near the town of Cloudcroft, and just down the way from Mayhill where I spent a week on my last sabbatical, you can find Sunspot, the national solar observatory. You might have heard about Sunspot in the news recently. It was closed and evacuated by the FBI three days before we got there, leading to all sorts of speculation and conspiracy theories. Turned out to be a criminal investigation of a janitor involved in child porn, and definitely not aliens. Gross. Any way, just around the corner is Apache Point, an active observatory that is home to the Sloan Digital Sky Survey, an important digital, 3-D map of stars and celestial objects that revolutionized the field about the turn of the century. No visitor center, gift shop, or tours, but the public is welcome to stroll around. So we did.

Monastery of Christ in the Desert

This is the bookend retreat for the sabbatical, balancing the week at the Sienna Center in Wisconsin. Molly and I spent three days and three nights with the Benedictine brotherhood at this monastery on the Chama River near Abiquiu, NM. It is a beautiful and remote setting. Most of the time was spent in silence, or a close facsimile, and we attended quite a few of the services of the hours. The brothers start their day with Vigils at 3:30 a.m. and Lauds at 5:00 a.m., and we managed to miss those somehow. We very much enjoyed our time in reflection there, and the night sky was incredible.

Moon Over the Monastery

Here are many repetitive pictures of the moon, Venus, Jupiter, and friends low over the mountains west of the monastery on two successive nights.

Acoma Sky City Pueblo

Molly’s mom joined us from Colorado when we returned from the monastery to Albuquerque. We spent a day at the Acoma Pueblo, about an hour west of ABQ. I had been planning to go to the Chaco Canyon Native American Heritage site, which is the remains of a very large community dating from about 800-1200 AD in northwestern New Mexico. Chaco shows a great deal of intricate astronomical knowledge built into the layout and architecture of the entire site. Unfortunately, the logistics of travel precluded getting everywhere I hoped to go, and Chaco fell off the list. Sky City was much more doable and turned out to be a fascinating side trip. The Acoma are thought to be descendants of the Chaco people.

The Very Large Array

The last of the Grand Tour observatories, the Very Large Array, is a bookend to the first observatory on my sabbatical, Green Bank. The VLA is the largest radio observatory in the world, a collection of 27 radio dishes, each 25 meters (82 feet) in diameter, set in a Y pattern with a 22-mile diameter. It is well known from Carl Sagan’s original Cosmos series and the Jodie Foster movie (based on a book by Sagan), Contact. Once again, radio astronomy proved to be absolutely fascinating, not only to me, but also to Molly and Mom who were both quite impressed. Good tour, good visitor center, nice gift shop.

And that’s pretty much it!

We spent a couple days with Mom at her place in northern Colorado, after which we took the train from Denver home to Harpers Ferry. I have some pics of the trip home here. I still have a couple places I want to get to in and around DC, but time is running out to get it in under the title “sabbatical.” Like I said, I hope to post more about the journey, things I learned, ideas I’ve pondered, observations I’ve made about life, the universe, and everything, so stay tuned.


Not Quite an Observatory: The University of Arizona Mirror Lab

My first tour in Arizona was the >University of Arizona Richard F. Caris Mirror Lab<, and you can see my pictures and comments at >this link.<

By this point I was becoming aware of the number of places I was visiting that pushed the limits of technology, knowledge, and skill for the sake of science. The Yerkes 40″ is the physical limit for refracting telescopes. LIGO is the most precise measuring instrument ever built. At this lab they craft mirrors that are smooth to one one-millionth of an inch. Such things are staggering to contemplate, at least for me.

While this isn’t an observatory, this lab is making observatories possible. They are making mirrors for the Giant Magellan Telescope being built in Chile, and they made the mirrors for the two optical telescopes on Mount Graham, which we will get to in a couple posts. >Here is a link< to a time lapse video, taken from inside the kiln, of the glass melting in the making of one of the mirrors. As far as I know, this is the only place doing work like this. There are other mirror labs, but nothing making mirrors this big.

This is also about the time I brought to consciousness a thought I’d had when I was in college working in a wind tunnel lab. Science smells like oil. We tend to think of science as being clean and pristine and airtight, or at least I do, but when you go to these facilities, the labs and the observatories, they smell industrial and oily. Big science in the real world, not your classroom stuff, is much more earthy than we see in the movies, with lubrication, and metalwork, and miles of wire, and countless boxes and drawers of spare parts. It’s not all theory and math and formulas. You need those, of course, but then you have to make them work in physical space.

That’s part of why I think we should focus much more on science, and space science especially, as a national economic priority. Science needs all manner of workers to make it happen. You need theorists, sure, but also technicians and skilled labor to put the parts together; fabricators, tool and die makers, welders and builders making the parts and things that hold the parts; construction workers building the work places and labs; plumbers, electricians, and painters to make the spaces workable; maintenance crews to keep it all in shape; administrators and clerical workers to organize it all; then you have to feed all those folks and provide housing and retail for them. Every big science project should mean work for hundreds or thousands of people with all manner of skills and all for the betterment of humanity. Decent work for decent wages should mean better opportunity and improved economic justice in communities. Better work and pay should mean decreased crime and need for social services. I know I’m an idealist, but am I missing something here?

But I digress. Here they make mirrors the size of swimming pools so we can see the farthest stars.


Observatory 6: LIGO

I’ve been keeping up better with recording my journey with my photos, which are now living at my Google account since I have an Android phone. Say what you will about the evil digital empires, it is convenient.

Any way, going way back to Louisiana and the LIGO facility, you can see my pictures and comments at >this link.<

Short form: >LIGO< stands for Laser Interferometry Gravitational wave Observatory, which consists of two campuses, one in Hanford, WA, and the other in Livingston, LA, where I went. It is an instrument that measures the distortion of spacetime by waves created by the interaction of supermassive bodies like neutron stars and black holes. It is a whole new way of looking at the universe, it is incredibly precise, and it is remarkably expensive. New technology is like that. We don’t know yet what the practical applications of all this will be, but I bet it will be cool.

LIGO Livingston is open to the public one day a month through their educational center. They have a very good collection of interactive displays aimed at kids and novices to help explain the science they do there. The staff are knowledgeable and friendly. Tours don’t really show you much of the actual instrument, as it is pretty inaccessible being encased in evacuated steel tubes surrounded by evacuated concrete tunnels. So you get to see the control room and the outside of the tunnels and a prototype of some of the pieces of the instrument. But somehow, that was adequate for me.

It is mind bending to think about waves in spacetime. They aren’t waves inside space but space itself waving. That means when the waves pass over the earth, the whole planet, your home, your chair, your body are all stretched and squeezed. You don’t notice because the effect is minuscule, but it happens nevertheless.

The universe is a weirder place than you would imagine.


This is tough

Just a quick note to let you know I’m still alive and well and on the trail. It’s August 27, and I’m in Tucson, AZ. Since my last post I have seen:

  • LIGO, the Laser Interferometry Gravitational wave Observatory, in Livingston, LA
  • The University of Arizona Steward Observatory Richard F. Caris Mirror Lab, where they cast, form, and polish the largest telescope mirrors in the world
  • Kitt Peak, the National Optical Astronomy Observatory, southwest of Tucson
  • the Heinrich Hertz Sub-millimeter Radio Telescope on Mt. Graham, Sufford, AZ
  • the Vatican Advanced Technology Telescope (yes, THAT Vatican) on Mt. Graham
  • the Large Binocular Telescope, also on Mt. Graham.

Today I’m driving to Flagstaff, AZ, to tour the Lowell Observatory where Pluto was discovered, among other things. I’ll return to Tucson tomorrow to catch the train to Los Angeles.

It’s a lot of travel, a lot of telescopes, a lot to take in, a lot to arrange, and a lot to write about. Guess which of those things I haven’t spent much time on? I promise to give you full coverage of all the events, complete with pictures – eventually. I may have more time on the train to catch up a bit, and maybe in L.A. and on from there. I can see the end of pilgrimage on the horizon, and I’ll definitely be able to do more writing once I get home. If I remember where that is.

Observatory 5: Yerkes, Part 2 – The Night Program Experience

Written at Sturtevant, WI, Amtrak Depot on Tuesday, August 14

Yerkes observing last night was awesome and strangely mediocre. It was amazing to use that venerable, world’s largest refractor and to see how it would have been used for science (more or less). The scope itself weighs 6 tons! And one guy can move it around with surprisingly little effort It’s that well balanced. Like at Allegheny (or probably the other way around), the floor is a giant elevator with the pier in the center isolated from it and the rest of the building. So we moved up and down all night. The floor weighs something like 36,000 lbs with 48,000 lbs. of cement counterweights around the perimeter. A small DC motor moved it up and down — the ORIGINAL 1897 motor! Similarly the original motor runs the clock drive (I think I have that right).

The main dome of Yerkes Observatory, home of the 40″ Alvan Clark refractor, still the largest refractor in the world.

Dan Koehler (KAY’ lur), the director of public relations and tours with whom I corresponded, led the program, as he has done for some 27 years. He is extremely knowledgeable and talked almost the whole time. (We started at 9:00p and ended about 11:45p.) With 18 people in the group we didn’t have huge blocks of time to stare but we weren’t really rushed either. You could look 2 or even 3 times at each object. We saw six objects: Jupiter, Saturn, M11, M17, M27, and M2. These were chosen for their various classes – planet, open cluster, reflection nebula, planetary nebula, and globular cluster – and their positioning. Dan gave detailed descriptions of each, specifically and by class.

The scope is 40” in diameter (the lens is, any way) and 63 feet long with a focal length of 19,100± cm. So the focal ratio is f/19, which means the field of view is tiny! I don’t remember the formula, but it’s really small. Good for planets, not so good for deep sky nebulae. We used a 40mm Explore Scientific (I think?) eyepiece, and that gave us magnification of 475X. It was a great big eyepiece – like a coffee mug or soda can – good for public viewing. Dan’s assistant (read: guy that does all the work) was named Chuck, I think. Let’s call him Chuck. Chuck would slew the six-ton scope around by hand to get it in roughly the right place, then check the giant setting circles (big wheels on each axis of the mount with coordinate system numbers), then adjust again to get about where the object should be by coordinates, then adjust the dome (and the floor as needed) to line up with the scope, then use the 6” finder scope, then jigger the thing to get the object centered in the eyepiece. It took up to 10 minutes for some objects. Dan advised and helped as needed and gave commentary. Then we would get to line up or blob up and take turns looking. We started with lights on, then level by level they were turned off.

Dan talked a little about the fate of Yerkes. He doesn’t know much for sure, but there is a group of concerned, local supporters that have been negotiating with UChicago. It sounds hopeful, but the lack of clarity and information is obviously frustrating to Dan and the others who are waiting to see if they will have jobs. Also, Dan reminds me a lot of Thom Lamb in appearance and manner.

After we observed the six objects, they brought the lights up and a bunch of us took pics with the scope. I got someone to take a couple of me, one looking at the camera and one looking into the eyepiece. The second is a pretty stupid picture, of course, because (1) the lights were on (2) the dome was closed (3) the scope was no longer even pointed at the shutters, all of which is plainly apparent. Oh well. The first one is a good picture. The evening ended pretty unceremoniously. I don’t remember if anyone even said, “Good night, thanks for coming.” It was just okay, that’s it, here’s the stair down to the door. Scientists are not always sentimental.

The 40″ Clark refractor and me

Me, pretending to look through the telescope and also through the dome wall with the lights on. Derp.











I stood outside for a little bit, letting my eyes readjust to the dark to see what the sky looked like. Pretty much like ours at home, I guess. I hoped to see a meteor before going, as the Perseid meteor shower had peaked just the night before, and eventually I pretended I did. It was midnight and I had an hour to drive after a long day, so I hit the road.

Details about the observations are coming up next.

Observatory 5: Yerkes, Part 1 – The Tour

[Ed. note – Yes, I know I missed writeups for Observatory 3: Holmdel and Observatory 4: Allegheny. They appear in my post >Picture this…<, and I will try to give them the full treatment eventually. For now, enjoy Yerkes!]


Written at the Green Grocer deli in Williams Bay, WI, on Monday, August 13

So I’ve just come from the >Yerkes Observatory< tour. Wow! What a beautiful place. I made the 12:30 tour, which starts with the history and the architecture o the observatory by a fellow named Robert who is writing a book on the subject. The 1895 building has a number of stylistic elements that remind me of Stewart Hall at PTS (c.1893?). It also has very many quirky symbols, faces, and pseudo-gargoyles to keep your interest for days. From there it was up to the main dome (of 3) to see the 40” Clark refractor. The setting is very similar to the Allegheny 30”. Similarly massive pier and mount and scope, similar elevator floor and dome track and such. Yerkes host Richard didn’t activate anything as Kevin (?) did at Allegheny, though. But, I’ll be back tonight to see it all in action! So excited! And even though I have no room for such, I bought 2 t-shirts. Because SO EXCITED! I’ll use a couple to wrap my icon to ship home tomorrow.

It is tragic that Yerkes is facing closure w/o funding. I don’t know how you find $20M to buy such a facility or the $500k/year to keep it up and open. I mean, that’s a lot of change, but to let such a resource for public science outreach languish seems unjustifiable. The location is too cloudy and light polluted for actual science, and the scopes are too small for cutting edge, or even dull edge science I suppose. It is 120 year old tech, after all, from the steam era. But photons don’t care. There must be some way to use the equipment for good. Then again, nothing lasts but the earth, and that one for another 4B years. You can’t keep everything. Where would you put it? But if you can make a museum out of a singer’s house in Memphis or even Winchester, VA, can’t we preserve such an important scientific site?

Meanwhile, I met another interesting person yesterday at the Meli Diner and Pancake House beside the Comfort Inn where I am staying. He was in the next booth and saw me writing in my journal. As I got up to leave, he asked if I were a journalist. Well, I mean, I was journaling, but I said no. A podcaster, yes, journalist, no. He asked about the podcast, so I told him it was religious stuff…. Pastor… sabbatical… blah blah. Well he was interested in it all, at least for the moment. Then I said, “I assume that you are a journalist?” Yes. He is working on a book about people who voted for Obama and then voted for Trump. Apparently, WI is a good place to find such. Also, being Paul Ryan’s districted added extra interest. So we talked politics a little. He gave me his card – Ben G_______ / New York / Beirut. Beirut? Yeah, he was there for 8 or 12 years. He says he thinks US is more interesting these days, though. Wow, okay! I rooted around and found my last business card and gave to him. [He said if he’s ever in the area he’ll stop by.] I’ll watch for his book.

Pictures from My Siena Retreat

I have so much to write about, and I’m so far behind! I hope you took opportunity to look at the pictures at the links I posted last time. I hope you enjoyed doing that, because I’m sending you another set the same way.  But not at the same place.

I got a new phone for the Grand Tour. A smart phone. My first smart phone. Yes, I know, but my old flippy was just fine and no one ever tried to hack it, I’m pretty sure. Any way, the new phone is also my new camera, of course. And in a major breach of Douthett etiquette, it’s not an iPhone but an Android-running Samsung thing. It cost about a third of what an iPhone would have been, so I got it. Fine, I’m cheap. I can live with that. But I digress. Any way, since it’s an Android, it syncs with Google Photos, so that’s where my pics are going at this point.

After a stupidly long train trip from Harpers Ferry to Chicago (6.5 hours late arriving) and another hour train from Chicago to Sturtevant, WI, I arrived at the >Siena Retreat Center< on Sunday, August 5. Siena is a ministry of the Dominican Sisters of Racine, and it’s a really lovely facility. There is still a convent there with a fairly small group of sisters who are faithfully living out their vows and their mission of praise, blessing, and preaching. I chose Siena fairly early in my planning process for the Grand Tour, as it is only an hour from Yerkes Observatory, and it looked like a beautiful site right on Lake Michigan with some interesting retreat offerings. These observations turned out to be accurate. It’s a beautiful place, a lovely setting, and I chose an interesting and challenging retreat.

The retreat I signed up for was about the only one I could fit into any plan for the Grand Tour that was open to men and Protestants. It also intrigued me. “Painting and Praying with Icons: Our Lady of the Sign” is what I selected. I remember when I was in seminary and we studied the Great Schism between the Eastern and Western Church in 1050 AD, which in no small part focused on the proper use or lack thereof of icons. It was the culmination of what I remember being called the iconoclast controversy. I sided with the iconoclasts, the side that believed icons were a violation of the second commandment. As with many things, I have mellowed on this issue a good bit. Nevertheless, the idea of actually painting (or “writing” as it is said) an icon and praying with it was definitely going to be a stretch! Spoiler, I did paint/write my icon, but its future in my prayer regimen remains in question.

So I have a collection of pictures from the retreat that are primarily showing the progression, step by step of my icon writing. It is a fascinating process, but a bit grueling for beginners to fit in a week. I expected that it would almost a paint by numbers process, and that there would be vary little room for variation from the proscribed structure of the icon. At our level of competence any way, this turned out not to be the case. While all (there were 17 of us in the retreat) of our icons are essentially the same, they are also wildly diverse in their style and detail. This is due to different levels of skill and experience in part, as some of us had never really done any painting before and some were 30-year art teachers. But it also was a product of choice and preference, and maybe also theological emphasis. Any way, in the end, the icons were as unique as the people in the room. I think this was a delightful outcome for our group and is also generally acceptable at the casual iconography level. If we were doing icons for a church installation, I think the rules are more rigid.

Let me say just a word more about the group. It was predominantly women and predominantly Catholic, but there were a few Protestants and a few men. Well, about three of each out of 17. Still. Quite a few of the women were sisters/religious, but only a couple were from Siena. One of the Protestant women was a pastor at Fourth Presbyterian Church in Chicago. Despite being in the minority in religious tradition, gender, and geography, I felt very much included in the group as a rule. Indeed, the group seemed to gel really well, being very supportive of one another and enjoying one another’s company. You know how in groups like this there is often that one person who is a thorn in the flesh? Well, unless it was me and I didn’t realize it, that thorn was not present.

Now, I did feel a bit like a stranger in a strange land in as much as many of the participants knew each other or knew the same people and places. Perhaps more than that were the distinct theological difference of belief and experience between Catholics and Presbyterians. The icon was of Mary and Jesus (more on that later), and my relationship with Mary is pretty academic. Meanwhile, for most of the Catholic folks, Mary is a present and active player in their daily life. For example, when we were finishing up, some of the women were complimenting my icon, and when I said I had never really painted before they were all the more impressed. One said, “She was really working through you, you can tell that!” I was caught completely off guard by this and had to spend quite a few moments figuring out who “she” was that was working. Of course it was Mary, but it never crossed my mind that Mary was as much author of my icon as its subject.

Okay, well, let’s get to the pictures. The link below will take you to an album full with some additional commentary on the process and the meaning of the icon itself, so I encourage you to go have a look. I say more about him in the album, but our instructor was Drazen Dupor from Croatia, and his website is >here<. Enjoyed getting to know him a bit.

Alright, alright. Enough talk. Let’s look at some >Platytera pictures<. There are a lot of near-duplicates, and some differences from one step to the next are pretty subtle, so you’ll have to pay attention. I’ll be glad to take your questions when you’re done.

And tomorrow, it’s on to the Yerkes Observatory, home of the largest refracting telescope in the world.
