Oh Yeah! There was that eclipse!

I was reminded at work today that I hadn't posted about the eclipse on the blog. Full moon indicates that the solar eclipse was 2 weeks ago, so guess about time to get off my duff! I did have a brief post on the Facebook, but time to document the event on a more permanent record! While FB is convenient for everyone to look at quickly, in 5 years if you want to see what you did, it is harder than heck to find it! I think that is where the blog excels!

Yes there was that solar eclipse! When I last left you, we were moving north towards the path of totality, visiting Meteor Crater, Lowell Observatory and Monument Valley. I had texted w/my buddy Melanie, who is Navajo, about where to go in Monument Valley. She had a meeting as we visited it, but as she was driving back towards the reservation, it was obvious we'd cross paths so met in a grocery parking lot in Utah. I thought I'd impress the Russian kids by giving a hug to a seemingly random female in small-town Utah, but they seemed nonplussed. Melanie and I worked together a decade ago when she was at the Mirror Lab. It was great to see her, if only for a few minutes!

We drove through some beautiful country up through Moab, overnighted in Grand Junction, Colorado, then north into central Wyoming. With the small towns, there were few places to look for motels, so we stretched our driving, arriving in Shoshoni a little after dark on Saturday for the Monday eclipse. I had warned our hostess Karen, and she had a pot of chili and cornbread waiting for us - a feast after a long day on the road. That is her in pink in the group shot at right. That tall good-looking fellow in the center is Karen's son Kevin, who is the local sheriff, and obliged the kids by taking them on a ride in his tricked-out sheriff's truck!

Karen and I had been concerned about keeping the number of people that she was hosting and cooking for to a manageable number. Even as we drove north, we met people who asked if they could join our party. We had 10 in our group, and a few weeks before eclipse, I heard a good friend and her family were outside the path w/their reservations, so got Karen's permission to include them - 6 in 2 RVs. Then the day before eclipse day, our buddy Bernie called and asked about joining us. I was originally going to depend on him as he had reservations in Wyoming AND Nebraska, and I was going to take the one he didn't use for our group. After Meeting Karen at the Grand Canyon Star Party, I didn't need his reservations. Turns out he didn't like the weather forecast and wanted to move west towards our group in Shoshoni. Hostess Karen overheard us telling him that he couldn't join us, and made us invite him and his what, 6 additional watchers, bringing us up to 22 that Karen was caring for (and using their one bathroom!). She pulled it off in a great way, and best of all said she had the time of her life taking care of us - can't hear better news than that!

My setup showing morning clouds

It's a solar eclipse Party!

I set up my mounting the day before the eclipse - I needed to align the mount to Polaris so it would track accurately on the sun. Since it was a big change from Arizona (43 degrees north vs. 32 degrees in Tucson), it might have taken a while, but fortunately I had preset it approximately before leaving. As a result, Polaris was in the field of the alignment scope, making for quick work. One of Bernie's group had an 8" scope and entertained Karen's girls and some of the neighbor kids with views of Saturn - impressive even under the streetlight we were set up under!

Eclipse day dawned partly cloudy, but mostly clear, so we all had high hopes of seeing a good eclipse. It turns out that the school across the road was hosting a national webcast of the solar eclipse that would appear on I believe the Fox Business channel. With all the international kids we had with us (my 6 Russians plus the two girls from my friend Karen (in the RV) who are from the Netherlands). They went over to take part in the online event, and totality in our yard was oddly kid-free!


The partial phases were a blur - I took a few photos, but was still concerned about running 3 cameras with only 2 hands! I also took a few photos of the group with my cell phone, though some used their cell phones to try to photograph the eclipse through the 8" scope or the filtered binoculars, with mixed success... This is Bernie in both of these photos checking the progress of the partial phase at left in the filtered binoculars, and taking a cell phone snap at right.

Most of the country observed some partial blockage of the sun. So the early parts are very similar all over the country. The color of the sky seemed to take on a weird cast as the sun slowly disappeared. While most of the country observed this effect most all stopped and reversed at some point, for us and those along the 60 mile or so wide path, we took a dive into darkness!


But the partial phases lasts well over an hour, so we got to lounge a bit, at least those who were doing visual observations. At left Bre and Michelle lounged and enjoyed a bag of popcorn while waiting for the REAL show to begin! Our hostess Karen, who thinks of everything, had a little popcorn machine setup for us!

At right, Bre and Roy do the promotional portrait. Unfortunately, I didn't take these photos, but I can't remember whose FB page I stole them from!






Finally the moon's shadow caught up to us in Shoshoni, and it was safe to observe the sun directly. Filters were ripped off and the corona of the sun was observed with the naked eye. It was glorious! This was the first eclipse I've seen in totally clear skies, and it makes a big difference! Bernie took video, and while he seemed to be easily distracted, it is fun to note all the changes you didn't notice looking thru the camera viewfinder, like the streetlights coming on, and the visual impressions people were noting, and of course, the screaming! Click here to go to his video!

As far as my photos go, the key to get good eclipse images is to take multiple exposures with different exposure lengths to record the full range of brightness, from the brilliant prominences that stretch out from the sun's surface, to the faint outer traces of the sun's corona, and in fact, the face of the earthlit moon! You often see the unlit side of the moon when it is a skinny crescent. It is caused by light reflected off the earth, and the effect is maximized at new moon - and you can't get any newer than a total solar eclipse! The corona shot at left is a combination of 3 frames of different exposures to better show how the sun's atmosphere looked to the eye. At right are the prominences that were very visible just before the sun's photosphere returned.  The red blips at the edges are mostly hydrogen carried upwards away from the sun's surface by the intense magnetic fields of the sun. These should be considered preliminary images as they were made from jpegs. I'm still working on the raw images that should be better...

I'm closing out with a flash spectrum - as the brightest part of the sun (photosphere) is just covered, the "neon pink" of the sun's chromosphere is briefly revealed. This transitional layer of the sun has an emission spectrum, where chemical elements are revealed by bright lines, as shown at the image at left. The red, aqua and purple lines are from hydrogen. The bright yellow line is from helium. In an instrument similar to my little spectrograph, helium was first observed on the sun before being known on the earth, thus the name (helium : helios, meaning sun). Unfortunately I hadn't noticed that the camera clamp had loosened at some point of the process and a large part of the spectrum is slightly out of focus. I'm going to look at these raw images too, and try some stacking techniques to sharpen, but I might just have to wait 7 years to the next solar eclipse in April of 2024!

So all-in-all it was a spectacular event. Those that ventured back out on the roads after the eclipse were treated to massive traffic jams. We camped out another day and by then the roads were fine, almost normal again. But it was certainly a highlight of the year!

On the Road!

The adventure continues!  My group of 7 Russians (1 adult and 6 kids ages 9-17) were in Flagstaff yesterday, now joined by my buddy Donna who is joining the eclipse road trip, along with primary drivers Margie and me!

We seem to always get a late start - perhaps it's the jet lag suffered by our visitors, but tough to get them out on the road before 9am. The goal of the day (after a big breakfast) was Meteor Crater! It is a cool place - overpriced, sure, but where else are you going to go to see a mile-wide crater carved out by a meteor? We spent a good 4 hours there, mostly 'cause they missed their first chance at a walking tour, but even hanging out there made it a better experience! Of course, the obligatory group shot at left s we drive up to it, with the raised rim of the crater barely visible behind them. A slightly better shot at right as we neared the place. Of course, the dirt from the crater had to go somewhere, and the raised rim is a dead giveaway. If you know what to look for, you can see it for more than 10 miles distance!

Once you step across the rim, the crater takes your breath! It is far enough across there is a little haze visible! At left Polina tries taking a selfie with the crater in the background... It is impossible to get into a single image, and unfortunately, I messed up in my panorama shots (yea, I do that occasionally). Taking an oblique shot like that at right is the best I did yesterday... Of course, with the sun so high in the sky there is a lack of shadows that makes the photos suffer as well.



There is a large public plaza outside the visitor center, and towards the northwest there is a wall with a huge window. Looking at it for an extended time, it looked very much like a painting or photograph that was hanging on the wall. Much like an outside observer gazing at a museum painting, it needed an observer in the scene. I was chatting with a woman passing by and she agreed to be in my photo and ended up with the view at left. The high sun again seemed to add to the pastel colors and lack of shadows (except the "frame" side of the wall facing me). It reminds me of many of my friend Ken Spencer who runs a Picture a Day blog, many from art museums where he includes observers in the artwork, and I get the same feel with this photo here... The view, by the way, shows the San Fransisco Peaks north of Flagstaff at left 40 miles distant.

At right, a distant group shot of our Russian friends, as they examined the Crater through scoped mounted on a platform some distance down from the rim.

We eased on back to Flagstaff and ended up at Lowell Observatory for their evening program. Highlight was expected to be viewing through the recently (well, 2 years ago) renovated mechanics of the nearly 120 year old 60cm (24") refracting telescope. Sure enough, after catching some science demos and meeting a friend which I'll write about in a future post, the Clark Telescope was indeed the highlight. For the first few hours of the evening it was pointed at Saturn and it was a quite inspiring view at what I guessed was about 200X.  The photos here were taken with some lights still on (didn't bother the Saturn viewing), and while it looked dark, recorded well in the 6D with high ISO and 16mm fisheye. The closeup at right shows one of our Russian kids at the eyepiece. We didn't quite close the place down at 10pm closing, but a bunch of tired kids (and adults) got back to the motel about 9:30.

This morning found us pushing north finally, headed towards the upcoming solar eclipse! It's been a while since we checked in on Polina's selfies - lets see where she is today... Monument Valley! Home of many of John Ford's classic westerns, it is a spectacularly beautiful place and a first time visit for me and definitely not the last! The Navajo have built an impressive hotel and visitor center facility there, and I'd love to have the time to sit there all day and watch/record the lighting change over the course of the day!

At right is a shot of Donna and Margie in her truck, that is hauling both kids and gear this week with me.



At left was the group shot - not all seemingly overwhelmingly happy, but at least seemingly swept up with the journey, if not the trip!

Finally we had to move onwards. My friend Melanie, is Navajo, and gave me a few hints of what to look for. One of the kids bought a photo at the gift shop of "Gump Hill", a scene in "Forrest Gump" that shows what appears to be a 10 mile long road terminating with an impressive set of stonework in the background. She said to look for it about 13 miles into Utah. Well, we got there and didn't see it, then finally notice it was behind me - we had just driven through it! Perhaps you recognize it, perhaps not... People were stopping and photographing each other in the middle of the highway - in this photo at right, I chose to photograph them. I noticed the woman's blouse and for all the world looked like she was starring in a slasher movie with a blood-soaked shirt. I even told her that as she walked past me, but then noticed the flower motif. I think she was taken aback at my slasher comment, ignoring the compliment I eventually paid!

We continued up through Utah, skipping Arches National Park because of time, through Moab and ended up in Grand Junction, CO. One more full day of driving to ge to the eclipse path!

A Few Miles Behind Us!

Day 3, and while I sometimes feel like tearing out my hair, our Russian buddies are here and we're on the road! Margie and I caravanned partway to LA on Monday to make the pickup at LAX (Los Angeles airport) a little easier. I'm not a fan of big-city driving, but LA was a challenge... Happily just using the map app on my iPhone, we found our way to LAX, and even on time! The poor part of the plan, was that it was near impossible to meet your party coming out of the international customs section. Sergey and his charges evidently came out while my back was turned and we ended up losing about 40 minutes because we had no way to connect... A serious defect in my opinion! Unfortunately with that delay, we got dumped onto LA streets right at 4:30pm, and it was stop-and-go driving for about 3 hours to get to the east side of town. Man - not fun at all! And unfortunately, while I'm driving for large sections of the day, not much chance to take photos!

Anyway, today found us just getting on the road and figuring that we could get thru Joshua Tree National Park as we worked our way to Flagstaff. In addition, it would give me a chance to surprise my friend Marker, who used to be our liaison ranger at the Grand Canyon Star Party, and just this year transferred to Joshua Tree. She ended up surprising me by being gone! She is on a 2 week break, and now that I think about it, mentioned taking time off for the eclipse to travel east. Oh well, I tried! Our Russian children are very well behaved and the six of them paid good attention at the visitor center before we headed out for some exploring. Group shots are obligatory, so that the folks at home can check in to make sure everything is ok! At left we are still in the visitor center, at right atop a rock...

Joshua Tree is an interesting place! The trees themselves are unusual, and the concentration of them in this one place is quite amazing! The geology too is unique, with large very flat plains, then these huge bolder assemblages sticking out of the ground. Someday when Marker's and my paths meet again, she'll have to do a brain dump on me to tell me all about it! The Park is also far enough from Los Angeles that they are promoting astronomy, holding a star party over Veteran's day weekend this November.

BTW, this boulder at the left of this image at right is called "the skull" from the "eye sockets" peering over the rocks in front of it...




Another obligatory group shot as we were actually leaving the park out the NE entrance. After that, we hit the road in earnest, getting about 450 miles in today - pretty good considering the late start and the hours at Joshua Tree. Heading north out of the park, we took a ranger's advice and took the "Amboy" road up to and through that near-ghost town. Located on old historic Route 66 there were some interesting salt flats, mining operations, as well as a singular volcano cinder cone - called Amboy Crater. Lots of interesting stuff over part of the country I've never seen before!

Of course, being the observant astronomers we are, even documented the shadow of the Earth rising into the east ahead of us. We're in Flagstaff tonight, perhaps Meteor Crater and Lowell Observatory tomorrow?

Start of a New Adventure!

Well today marks the beginning of a 2-week adventure! Not only am I on a road trip to observe the upcoming solar eclipse crossing the country, but I'm doing it with an astronomy group from Krasnoyarsk, Russia! Last time we saw Sergey, he was escorting 11 Russian "children", as he calls them (ages 9-16), as I was in charge of their itinerary while we did astronomy stuff in Southern Arizona for 9 days! As I write this, I'm in Blythe, CA, getting part of the trip behind me so I can pick them up at LAX early tomorrow afternoon!

This time there will only be 6 kids, I believe, as well as Sergey, and since my van only sits 7, I've managed to talk a friend of mine, Margie Williams, along as a secondary driver with her pickup and jump seat. That way she'll be able to haul some gear for me and also load a passenger or to. The trip is rounded out by our friend Donna who mostly wants to see the eclipse, but also wants to experience the trip with us as well, and having a 3rd adult can't help either!

But besides playing tourists on a road trip, there is an eclipse to observe! Since we are driving, we're not limited by airline weight or size limitations, and I've got a bunch of gear totally suitable for an eclipse! Shown at left is a view of the 3 main scopes, all mounted on a single beefy AP 1200 mounting. The main scope is a 5.5" diameter refractor which will give an excellent image on the full-frame Canon 6D sensor with its 1,000mm focal length. Next to it is a much-wider field of a 300mm lens on an APS sensor. The "tilted" scope at left is actually a spectrograph with a beefy prism in front that will take a spectrum of the sun's chromosphere at 2nd and 3rd contact - something fun to do! At right is a view from the other (top) direction!

And along the way, we'll be making some first-ever visits to some states for me (Wyoming, Utah), and we'll tarry long enough to see some of the sights as well, though plans call for us to be back in Tucson a few days after the eclipse to visit some of the "old standards" that amateur astronomers would come halfway around the world to see. It all starts tomorrow, or started today - depends on how you count! Stay tuned!

August finds AZ Bustin' Out!

I got back from the Midwest last week to find Arizona as green as I've ever seen it! Even flying into the Tucson valley, the mountains were a rare emerald green! Evidently the month of July had been the wettest on record - of course, the rain stopped as soon as I returned! My back yard is usually a bare dirt sort of yard, but I returned to find 2 foot high weeds in desperate need of whacking!


With all the water, many of the cacti here are blooming again, some for the second time. In front of the house I have pair of barrel cacti, both at least 25 years old. They look pretty much identical, but one only blooms in the Spring, the other in the Fall - no confusion there! The normal Fall-blooming one (well, mid-August anyway), was budding heavily with the first flowers - well mixed with the yellow fruits from last year's flowers! The image at left reveals the first flower, well-hidden among the buds about to flower and the fruit from last year, and perhaps before! At right is a close-up of the flower. As with the last post of the Katydid, these images are all focus-stacks, where multiple exposures were combined to extend the range of sharpness. This close-up of the barrel cacti flower was constructed from 28 individual frames!

Since the largest image I can display on the blog is 1600 pixels wide, both the above images were reduced in quality for display. But here at left is a full-resolution of the flower, cropped from the original image. Note how the center part of the flower (stigma?), looks all the world like hot dogs encased in buns!








Out in the back yard, my favorite cacti are the array of Cereus Repandus plants along the east end of the house. One of my favorite monsoon activities is to monitor them as they open and watch for pollinators. Seeing 5" wide Rustic Sphynx moths attack these 6" wide night-blooming flowers is really interesting! However, the problem is that my next adventure (eclipse road trip!) starts in a few days, and while the plants are covered with buds, I'm not sure any of them will open before I need to leave! Fingers crossed there will still be some available to bloom upon my return in a couple weeks!

And almost hidden behind the grill, I remembered my little potted barrel cactus, and I almost missed it even though in full bloom! It's dark red flowers are not particularly conspicuous - I'm not sure I've seen flowers less conspicuous, unless you go with the green cholla cacti flowers! Shown at right they are a quite nice shade, and I see buds for future blooms - I'm just not quite sure what I'll see next time I'm home! Will be glad to give up the 2 foot high weeks though!

The Hitchhiker!

July was a bit weird at "Ketelsen East"!  The past few years I've spend time almost daily searching for and finding some of the weirdest bugs I've ever seen! At left is a composite showing some of my favorites the last couple years - all taken within a few yards of the house! But this year, whether the cool spring or wet weather, there has been NOTHING to be seen! Searching the same areas I've taken images of the insects at left have revealed almost nothing!

The other day after my bike ride, I drove into town to pick up a morning NY Times and gas up the car. I immediately noticed a hitchhiker atop the car - a Katydid! Now I've seen these before in the woods, but found them pretty shy and tending to avoid me when I get the camera out. Even when using my cell phone to take the image at right at the gas station, he was constantly moving away from me. After the snapshot, I ignored him and drove home - about what, 5 miles away.

So I was surprised upon arrival that he was still there! He must have found somehow to hold on tight to withstand the 50mph speeds I got up to. Perhaps from that very buffeting, he was pretty docile and I had time to go get my good camera (Canon 6D), macro lens and about 30mm of extension tubes. Still atop the car, I couldn't use my tripod, but used the top surface to brace on and shoot him. The result is at left - the dramatic lighting is due to his being under a cross-brace of the car rack, so was in it's shade, most of the light coming in from behind him.

Note that this photo, as well as all of the photos above, are "focus-stacked". Several-to-many images were combined, all focused at slightly different zones to extend the depth of focus of the image. It is almost necessary at this magnification, and in this case in the left image, 24 frames were combined in Photoshop to keep much of him in focus. The image at right shows one of the individual frames, shot at F/8 - a moderate aperture to let in light yet minimize diffraction effects. Note that only his right shoulder and left leg are in focus, most of the rest of him a little out of focus. You might have to click to load a larger image to see the differences.

Focus stacking is a powerful tool! Think of the work that Photoshop has to do to align all the images (these were handheld, braced against the roof of the car, but there was motion of the camera between frames while I made slight focus adjustments). Note also that the magnification changes slightly as the focus is changed, so the scale has to change too when they are combined. Then they take only the sharpest part of each frame and reassemble the image. It does pretty well too - check out this full-resolution crop of the focus-stack, showing detail in its compound eye!

I was able to take one set of images for stacking, went to get out of the strong sunlight to examine them closely, then repeat for this set of images. After spending 10 minutes to download them and stack them, I went back out, but he was gone by then. But it was fun to get this fellow w/just basic tools of camera, macro lens and Photoshop - not even a tripod...  He may well be my only "get" of the Summer!

Out And About!

While at "Ketelsen East", I always enjoying staying at home out in the woods, but friends and family are only a couple hours away, so usually hit the road pretty often. My family is mostly just west of the Mississippi River, so an even 2 hours away, and we usually reserve Sundays for the drive to visit brothers and sisters, usually while eating at a local restaurant. With such a short drive time, I usually sleep in my own bed, so usually leave our dinners by 8pm to get home at a decent hour.

Case in point was early in this last trip when my brother Jim hosted us for a pool party on a Sunday. The "excuse" as if we needed one to get together, were for the July birthdays - our step-mom Diane, sister Kathy and great niece Alivia. At left they get to share a cake, made by my niece Marsha who works in a bakery.

A secondary excuse was that Jenn (my niece) and husband Chet were visiting from Connecticut! I remember their wedding in Des Moines 15 years ago (Happy Anniversary!). While a few years old, I believe it was the first time I'd met their son Sawyer, shown at left playing in the pool with his dad.

And if we needed any more reason to congregate, two of my college buddies happened to be along! Shown at left, Michael Dorn at right had visited Melinda and I a few years ago and happened to be out that weekend visiting me again. He met my family on a trip to the ancestral farm 40 years ago and wanted to join us again. The fellow in the white shirt is Luke Kuhl, who was my college roommate for 2.5 years at Iowa. He got more than a little ribbing for his name, since we went to school right after the movie "Cool Hand Luke" was popular! I hadn't seen Luke in close to 6-8 years, so was great to catch up - the 3 of us lived in the "Penthouse" 5th floor at Hillcrest Dormitory back in Fall of '72! Always fun to observe how nobody ever changes!

A few days later and I was doing a road trip. It had been a few years since Melinda and I had visited my friend Beth and Phillip in Minneapolis. It was definitely time to do another visit. Beth is one of my dearest friends again, going back to college days 40 years ago. She and Phillip survived a horrific car crash 15 years ago that left her confined to a wheelchair. But thanks to technology and her service dog Mika, it doesn't slow her down much. We made a trip to the Arboretum, one of her favorite places, as well as a restaurant overlooking the Chaska Curling Center where the USA curling team practices and competes! We also took advantage of Phillip's bar-b-que expertise - that is him at left in their garden of a back yard...

At right is a shot of Beth and Mika. I've never seen a service dog at work, and it is pretty amazing what she can do from opening doors, calling elevators, picking up items Beth needs. She is very well behaved and obviously they have worked together for a long time. It was hard to say goodbye, but eventually it was time. Phillip took our photo together, and like my selfie "rule of thumb" - it will come out fine as long as you have someone gorgeous next to you!








On the return trip to "Ketelsen East" I had intended to stop in Cedar Rapids, Iowa to see some of the crew from my old RAGBRAI bike team. That Friday they were going to load the bus for the trip to western Iowa to ride back across the state over the next week. Unfortunately, there was bad weather on the way, so didn't stay till evening to visit, but did pause nearby to see my nephew Jeff, wife Sandy and their beautiful daughters. Claire, shown at left, had just lost a front tooth and is showing the note from the tooth fairy. Because of her bravery in pulling it out, the tooth fairy left her money with glitter on it! Her younger sister Natalie was off to the sitter most of the day, but I got to see her just before leaving for the storm, as shown at right. Again - selfie, someone gorgeous - successful shot!

I stayed just ahead of the storm for the 3 hour trip back towards Chicago. Away from home for a few days, but with lots of memories of friends and family...
