Blackout Rally recap

300-plus Airstream trailer enthusiasts—many members of the Oregon Airstream Club, Greater Los Angeles and NorCal units of the Wally Byam Airstream Club—camped together at Lake Simtustus in Madras, Oregon to await the Great American Eclipse. To kill time before totality, a 3-day party was planned that included an eclipse presentation and evening telescope starparties with astronomer Brian Bellis from California, a drawing class, a geology lecture, catered meals each day, Cachaça spirit tasting at happy hour, live entertainment (Antsy McClain from Nashville!), and a “Day on the Dock” party hosted by Airstream Adventures Northwest (Airstream Inc.’s #1 dealer).

Day on the Dock included a fishing derby, water toy relay race (involving a hydrobike, kayaks, and an SUP), incredible prizes, a big ol’ freezer of free ice cream, and a “Hot dogs for Hot Shots” fundraiser for local firefighters who have been working overtime this season to prepare for the eclipse in Central Oregon. (The Oregon Airstream Club raised well over $2000!)


On Monday August 21 all eyes were on the sky as we gathered together to await totality, wearing our custom eclipse glasses. Several rocked tin-foil hats.

At dawn on eclipse day I glared at the thin haze in the sky, and the brownish accumulation wafting from a wildfire on Warm Springs reservation toward our viewing location. “I’m not a fan,” said astronomer Bellis, and the eclipse chasers and telescope buffs agreed that the advertised crystal blue sky of Central Oregon was not to be that day—but visibility was improving with each passing hour and everyone remained hopeful and excited.

Several telescopes were positioned to study the significant sun spot activity and the big prominences. Bellis brought a terrific “funnel projector” and an attendee made a nice pinhole headbox. Lots of folks brought colanders from their Airstream galleys to observe rows of neat and orderly crescent projections. After planning this event for seven years, it was finally going down.

The phenomena occurred on cue as 10:19 a.m. approached: sharpened shadows, eerie changes in the light, and even shadowbands—my first viewing ever, collected on a big piece of white foam core.

What a thrill and blessing to hear the gasps and cheers of 350 people when totally slid into place after a dazzling diamond ring. (Post-eclipse regret: why didn’t I make an audio recording? Hopefully someone else did.)

Something amazing WAS captured on video and in a still shot by one of the guests: during totality, a skydiver sailed right across the eclipsed sun. I hope that guy makes some good money selling the image to Astronomy magazine.

The coronal streamers were only slightly diminished by the haze, and at third contact the crowd cheered again and many brushed away a tear or two. I held it together until someone crying ran up to give me a hug. Sharing the beauty of our planet with other Earthlings and feeling our place in the solar system and the universe together always touches me deeply, and I try to carry that feeling forward until it refreshes during the next eclipse. (2019, ya’ll.)

After totality we enjoyed a catered brunch and a champagne toast delivered by special guest Thomas D. Jones, NASA astronaut/spacewalker. He delivered a fascinating presentation about the ongoing role of NASA missions, answered questions about what it’s like to live and work in space, and stuck around to autograph books and inspire kids.

Until next time, clear skies!

Superbloodmoon bust


Telescope positioned in the driveway? Check. Camera charged and lens changed? Check. Wagon full of filters, extension cords and PowerTank? Check. Drink poured? Check. And…no moon. Where are you, moon? I doublechecked her position with StarChart and—after arguing with a neighbor who said he just saw it out his window and it’s rising in this direction not that direction—I concurred and moved the whole awkward shootin’ match to the back yard. Still no moon.

After much hiking around our tree-lined property we finally glimpsed the dim, fully eclipsed moon, almost completely obscured by the tall pines to the northeast. Crap.

What’s that old adage I just made up? “The worst night for astronomy can turn into the best night for drinking.” The evening was mild, the rest of the universe was on glorious display, and the moon finally rose between two trees shortly after totality, letting us enjoy a few minutes with the telescope.

No time to experiment with the camera—the bright white crescent at the bottom was rapidly pushing away the red eclipse and Ms. Moon was hurrying to move behind another tree. (Why do I even try? Others capture these events beautifully. Nerdist published some pretty shots.)

I barely had time to try a lunar sketch. Guess what? Drawing a supermoon is not super easy. I wasn’t using the scope drive so the damn image kept MOVING out of the viewfinder, and juggling the red flashlight on my iPhone, my eyeglasses, three drawing tools and a pad was like a Mr. Bean episode.IMG_7095

Well, I have eighteen years to practice.

Getting geared up…

Celestron…and a little apprehensive about tonight’s supermoon eclipse. I’ve promised the neighbors a driveway spectacle: viewing the biggest full moon of the year, eerily reddened by Earth’s shadow, as seen through my Celestron 8 SE.

Totality peaks at a reasonable 7:11pm, Pacific Time. (Seven eleven…hmm, the date of my first total solar eclipse. Bodes well.) Beginner tip: Always refer to the astronomical date and times as reported in your local newspaper. If your paper is lame, doublecheck with another local source. I nearly had a heart attack learning that the eclipse would be on Monday while I was reading Sky at Night—published in the UK.

I’ll set up early and paw through my eyepiece collection to make sure I have the right one well in advance of the arrival of the spectators. I don’t think I’ll need the clock drive. (If you can’t track to the moon, your telescope privileges should be revoked.)

Looking forward to viewing the darkened blood moon, which I assume will reduce the light blowout that makes observing a full moon difficult. Skies are clear here in Central Oregon—should be a beautiful night. I’ll try my hand at a lunar sketch, using this tutorial.

Now: to concoct a drink recipe for tonight. Suggestions? I’m thinking something red…

First-timers guide to looking at the sun with the Celestron 8SE

Big filterIf you own a nice telescope outfitted with solar filters, you’re probably an advanced enough user not to need these dumbed-down, step-by-step instructions. If, improbably, you share my situation—an absolute noob with a big, complex scope on her hands—I offer the following easy, lowest-tech way to align and track to the sun.

All thanks and kudos go to Grant Tandy, Astronomical Interpreter at the Oregon Observatory at Sunriver. During a practice session with Grant I learned that the alignment process—contrary to the marketing prose at—is more finesse than precision. One of the most valuable and consoling takeaways during the guided viewing with Grant was discovering that “close enough,” “keep trying, it’s hard,” “just turn it on and off and start over,” “it takes practice,” and “you’ll get used to it” are all acceptable stargazing concepts.

Do I need a solar filter?

Oh hell yes. Unequivocally. Without it, you’ll destroy the corneas of your eyes, and the plastic gizmos inside the telescope will melt. The solar filter reduces sunlight to the optics—both yours and the telescope’s.

What kind of filter should I get?

There are two main types: “white light” and hydrogen-alpha (“H-alpha”). Without going into detail, a white light filter allows you to see sunspots and some textures in the photosphere. They’re great for the safe viewing of partial solar eclipses, and the transits of Venus and Mercury. You’ll see a white image of the sun (or sometimes a yellow-orange color).

With an H-alpha filter you’ll observe all of the above, plus solar flares and prominences. Thusly, they cost a lot more; expect to pay up to a grand for a high quality system. The H-alpha filter transmits only one wavelength of light in a deep red color, and that’s how you’ll see the image of the sun.

I selected the two-part H-alpha system from Thousand Oaks Optical for use with my 8SE. It includes the energy rejection filter (ERF) that fits over the business end of the telescope, covering the aperture, and the H-Alpha filter unit (HAU), which acts like an eyepiece. The HAU and ERF are always used together, and the following steps include installation of both. (“Installation” is strong. They just pop into place.)

Where do the filters attach on the scope?

It’s safest for your telescope to be indoors, in the shade, or at the very least pointing well away from the sun when you’re changing solar filters. Just remove the plastic protective cover from the front of your telescope, and replace it with the big solar filter cap/energy rejection filter (ERF). Position the circle cutout at the top, at 12 o’clock. Then remove whatever eyepiece you were last using for nighttime viewing, and insert the solar eyepiece/H-Alpha filter unit (HAU). It works in tandem with a regular viewing eyepiece.

Select the right eyepiece.

Splurge on the the Celestron accessory kit, a nice assortment of five eyepieces, a Barlow lens, and a bunch of fun filters in a sharp little metal case. (We experimented with the Barlow for X2 magnification, but settled on the 32 millimeter for solar viewing.) All right! Let’s look at the sun!

Bring the telescope outside where it’s sunny.

Do this on a clear day, of course. Carry the scope (it’s heavy) from the base, where the battery compartment is. Bring along your eyepieces and the PowerTank if your extension cord won’t reach from the source of the shore power. Turn the telescope on. (The power switch is at the base of the fork arm.)

How do I align the telescope directly to the sun without risking my eyesight?

Good question. You could stare right up at the sun to see exactly where it is in the sky, but that’s not a good idea, is it? Use the shadow of the telescope on the ground as your guide.

controllerBut first, you’ll be using the computer in a minute, so check the settings. You’ve probably already used your NexStar hand controller to key in the date, time and location. Run through the setup procedures again to make sure the correct data was stored; you might have to update the time.

Press “Enter” to begin alignment.

Use the scrolling arrows on the hand controller (the small arrows, not the big PlayStation-style ones that move the telescope) to find “Solar System Align”. Press enter. (It may ask for the time. If it displays as correct, press enter.)

“Select Object”. Scroll to find “The Sun”. Enter.

See an ominous warning: “Do not look at the sun without the proper filter.” We’re good. Right? Better doublecheck. (I wonder how many people per year fry their eyes this way. Probably during a solar eclipse it’s chronic.) Press enter.

Now use the big direction key arrows to tilt the scope up toward the sun. Watch the shadow of the telescope on the ground; angle it around, looking at the different shadows made by the optical tube. If it’s a sausage-shape, you’re not quite there. An oval? Closer. Stop when the shadow is as perfectly round as you can get it.

Scope shadow

Now set the telescope to track the sun.

Look into the solar eyepiece. If you’ve nailed the shadow, you’ll see a small-ish, spot-on, perfectly centered image of the sun. (It’s fine if it’s off to the side a little).

Don’t panic if you see a cookie bite in the sun at first. There isn’t an eclipse in progress, that’s just the solar filter. That bite will go away when you get everything aligned and are using the right eyepiece. (Make sure the mirror circle of the big solar filter is toward the top.)

If you don’t see the sun, do you at least see a shadowy, ambiguous patch of red? Good. That means the sun is just off to the edge of the filter, and you’re very close to where you want to be. Slowly tap the arrows in each direction until the sun appears. If you see more red coming into view, keep going in that direction.

Insert the viewing eyepiece.

EyepiecesAgain, we recommend the 32mm. “It gives you a bigger view,” advised Grant. Indeed, the ball of the sun nearly completely fills the eyepiece with the 32.

Dock it on top of/behind the solar eyepiece. You can’t screw this up— they only fit together one way: solar first, viewer second. Secure them both by tightening the little silver knobs. (Not the white plastic knob. That’s a focus adjustment. More on that later.)

Look into the eyepiece: now you’ll see a big image of the sun. As it’s so large, you’ll have to align it perfectly to keep it in the middle. Use the right/left/up/down direction key arrows to zoom the view around until the sun is centered. The controls seem counterintuitive at first, due to the diagonal of the mirror that flips the image of the sun. You’ll get the hang of it. At any time you can slow down the motor speed as needed. (Press the motor speed/rate button, then a number on the keypad, like 4, or 6. No need to press enter.)

As soon as the sun is centered—doublecheck one last time that the full image of the sun appears centered in the eyepiece and hasn’t wandered away—press “Enter”, “Enter”, then “Align”.

“Align success”! If you went through the process correctly, and the sun was pretty well centered in the eyepiece, the clock drive will take over and the telescope will now track the sun to keep it centered. From here, you can fiddle around looking for sunspots and flares at the edge. You can fine-focus even while the telescope is tracking.

What if it’s not tracking?

The sun was probably not perfectly centered when you selected the final alignment buttons. Just go through the process again. Or swap eyepieces and try again. The alignment may never be perfect, and you might have to re-center the sun every five or ten minutes. If you’re actively observing, minor tweaks will keep it in alignment.

Lost the sun? Remove and pocket your viewing eyepiece and look back through the solar eyepiece to locate the red area again. Completely lost? Turn off the telescope for ten seconds to reset the computer.

If you go in for a sandwich you can always come back and start over. Just keep trying. A person I’m close to—I won’t say who, but it rhymes with my smushband—will always default to “this thing is broken!” after about two minutes of failure. “This equipment is very technical,” assured Grant. “You have to play around with it.”

Note that you don’t NEED to set the scope to track. You can make continual minor swiveling adjustments with the direction keys to keep the sun from floating out of view if you’re not using the clock drive. Don’t forget that you can change the swivel speed.

I’m having trouble seeing.

“It’s tough,” said Grant. “With the way the eyepieces are angled, and especially during the day, it’s tough to get your eye on it.” You might be seeing a floating red ball, a blob like mercury in a thermometer, your own eye, your eyelashes. Sunscreen may be running into your eyes. A sun shade might help but I don’t think Celestron sells one for the 8SE. Just relax and keep at it. If you wear prescription eyeglasses or sunglasses, look into the eyepieces without them on. I cup my hand over my non-viewing (left) eye to avoid squinting and distortion.

Damn it’s hot out here in the driveway.

Yes, it is. Hydrate. Don’t worry about your scope so much. It can take the heat as long as you’re out there with it.

What are those black discolorations on the surface of the sun?

Sunspots! You’ll see them alone or in a cluster or sunspot grouping, caused by the magnetic field of the sun. To put their size into perspective, envision that the diameter of the sun is about 110 Earths, side by side across. A nice visible sunspot is about the size of Earth. On an “active” day you’ll see more.

Now look for prominences.

Scan around the edge of the solar disk. If you see a misty, foggy rising, turn the little plastic white knob this way and that to bring the prominences in and out of focus. Use it in tandem with the big black focuser knob at the base of the optical tube…whatever works. This won’t disturb the tracking.

If you’re well-focused on prominences, you’ll be in a good position to clearly see any sunspots. Both are related to the erratic magnetic field on the sun, which causes random jets of hydrogen to come out (as a prominence), or, less commonly, as a big flare or loop.

“Most prominences are not very prominent,” observed Grant. Don’t see any? Maybe there’s just not a lot of activity today. Try again some other time.

Fun fact: When you see a prominence, you’re seeing it eight minutes ago. That’s how long it takes the light from 93 million miles away to reach us.

Adjust your expectations. 

Though a prominence is actually moving like a flame or a geyser, you won’t see it that way “because it’s on such a large scale,” explained Grant. “If you think about a prominence—an average, kind of medium-sized prominence—it’s about 40,000 miles across. If it’s moving 2000 miles an hour, you’re looking at it moving 1/20th of its total distance in one hour. So you see just a small fraction of it move in an hour. If you were to come back six hours later, you’d see more of it has moved.”

There are so many filter-enhanced and computer generated astrophotos in Discover magazine and on Instagram and elsewhere online that you might be disappointed in the actual view through your eyepiece. Try to maintain perspective—you’re a speck standing 93 million miles away, looking at flames on the sun. That’s pretty cool.

I still can’t get this frickin telescope to work.

How I Learned to Stop Worrying and Love My Telescope

Solar scope GrantI do love my Celestron scope. The NexStar 8SE wasn’t too hard to assemble. It really makes a statement as a decor focal point in the dining room. And it would pull in most of the go-to night sky objects, up close and personal—from the cool lunar craters, to Cassini’s Division in Saturn’s rings and the Great Red Spot, even the M13 cluster—if I could figure out how operate the damn thing for maximum enjoyment.

Likely due to the price tag (it was gifted to me by a very generous father-in-law), that level of telescope assumes a basic operator knowledge that I frankly don’t/ever will have. I never passed through the kiddie-stages of owning smaller, less complex scopes. I haven’t yet read Astronomy For Dummies. I can’t point to Polaris. As dense as it is, the paper documentation that comes with the 8SE still reads a little like the Monty Python “How To Do It” sketch. How to play the flute? “Well, you blow there and you move your fingers up and down here.” How to use an 8-inch altazimuth Schmidt-Cassegrain telescope with a SkyAlign’d clock drive, Barlow lens, assorted Plossl eyepieces, filters, power tank, and energy rejection/H-alpha solar filter system? “Well, you point it there, and you push this button here, and then you start looking at the Solar System.”

Well, there are few more steps. My husband, neighbor, and I all flailed around on multiple occasions, late at night, trying to properly align to the stars and planets. The only ones we’re sure of are Saturn and the moon. There’s more to see, I think.

There are one billion—no wait, TWO billion resources on the internet to teach me how to operate my telescope. But who has time to wade through all of that, most of it over my head anyway? I set out to find a tutor, and a wonderful one I did find.

Meet Grant Tandy, Astronomical Interpreter at the Oregon Observatory at Sunriver. He agreed to help me set up my scope for solar viewing (a function I’ll need to master within two years, before TSE2017) and teach me to find and appreciate nighttime objects as well.
