Eclipse: Tired, dirty, and happy

The Sun at Maximum Eclipse - 2:32 PM EDT - Note Sunspot at Lower Left

Yesterday (August 21) millions gathered along a thin path crossing the continental United States to watch a total eclipse of the Sun. Those with favorable viewing conditions along the path of totality enjoyed an amazing sight and experience. Totality fell close enough to a west-to-east center line across the continent that at least a partial eclipse was visible to anyone with access to clear sky.

Since, with some self-doubt, I had decided not to travel to the path of totality, I organized the Hiram Eclipse Watch event. With the support of the Hiram College Physics Department, it took place on the campus of the college.

I set up two telescopes: a six-inch Meade refractor with a Baader Planetarium Safety Herschel Wedge, and a 90mm Meade refractor with a Thousand Oaks glass/metal filter. I also went equipped with my Canon EOS 50D camera, 400mm telephoto, and 2X teleconverter (>1,200mm focal length equivalent), and white light film filter. Physics staff ran a Lunt Ha scope and an experiment recording temperature and solar energy changes during the eclipse.

Summarizing, despite last-minute worries over cloud cover, we had clear to partly-cloudy skies for the duration of our 80-percent partial eclipse. An estimated 375 visitors came out to share the experience, and by all reports had an excellent time. Some families even brought blankets and enjoyed a picnic on the lawn in the shade of old trees!

It was very hot and fairly humid and I labored in the sunshine erecting and operating the telescopes, rationing out eclipse viewing glasses, explaining the eclipse event and solar features, and making a few photographs of my own. By the end I was dripping with sweat and very tired but had to rush home to process and upload a photograph of maximum eclipse to a newspaper.

By the end of day, I was was tired, dirty, and happy.

Moon and Milky Way

Milky Way and the Moon - the "Tea Pot" of Sagittarius and constellation Scorpius are visible on opposite sides of the central tree. The bright star above Moon is Arcturus.

The Cuyahoga Astronomical Association hosted a public star party the night of Saturday, July 29. While I did not take my telescope to the event, I was happy to have attended and brought my camera setup. I spoke with several people, answering questions about the night sky and pointing out a few areas of interest. I was also able to observe planet Mercury through one of the club's telescopes. The tiny world was in a crescent phase - the first time I've witnessed that (Mercury can be very difficult to observe due to its proximity to the Sun and obstructions along the local horizon.). Aside from viewing Jupiter and Saturn via others' telescopes, my main interest was trying out my camera and lens setup on the Milky Way.

Moon - July 29, 2017

Light from the waxing Crescent Moon and from the nearby city of Medina made the Milky Way's star lanes appear as misty clouds but they were more noticeable in photographs. I hope to return some time soon, on a moonless night, and make a few more efforts at local Milky Way photography before human-made light pollution makes it impossible.

Sadly, not much observing to report over the past months! The demands of "real life" helped distract me from the night sky. Weather - cloudy and rainy skies - have provided the worst issues. That is, if you ignore the fact that the handbox controller failed hobbling my six-inch Meade refractor! I was able to locate and purchase a replacement for the failed handbox and a recent test showed it to be an improvement; it's better than the original!

Most of my observing attempts have been through Open Night events I hosted, or attempted, at Hiram College's Stephens Memorial Observatory. The big refractor there isn't computerized but its nine-inch objective lens gathers plenty of light and is very contrasty. The sky in Hiram, on a clear night, is darker than in the cities allowing the Cooley Telescope to deliver excellent views... when weather permits!

Highlights of the year, so far, were observations from Stephens...

On May 20, on a night threatened by cloudy skies, I observed Jupiter and its Galilean Moons. The best sight of the night, however, was seeing the Great Red Spot rotate into view from Jupiter's limb. Cloud banding was also seen: the equatorial bands and traces of other atmospheric features.

The night of June 24, following evening storms, Jupiter would have been visible from Hiram but quickly dropped behind neighboring trees. Hit of the night was excellent viewing of M57 - the Ring Nebula. The view was clear and bright where usually the ring appears as a dim "gray donut."

July 22: Partly- to mostly-cloudy skies after daytime storms allowed brief decent viewing of Saturn. The seeing was unsteady but I was able to glimpse Titan and several of Saturn's smaller moons, the Cassini Division, and some atmospheric banding! The rings were tilted at an open angle allowing optimal viewing.

See the weather theme?

And that's pretty much it! Recent years and, particularly, last year and this (so far) have seemed increasingly cloudy at night. I'm hoping my efforts to improve observing from home will allow more opportunistic viewing; future efforts may include building a tall, permanent telescope pier or purchase of a new telescope of Cassegrain design ... the long refractor's eyepiece demands neck strain as I point the scope higher towards the zenith to avoid serious light pollution here!

Waiting for dark

Wow! It has been a long time since my last post, nearly a year! I'm going to have to review the past year and catch up. For now, I'll simply record the fact that this year looks good for personal observing. Today I set up my big personal telescope to make certain everything was present and in working order. I tested the Safety Herschel Wedge by looking at a somewhat hazy Sun. Then I parked the scope, now waiting for dark. Only "fair" seeing conditions are expected tonight, and we've plenty of light pollution. Still, the big scope is set up for testing after a long time in storage. If alignment is good enough I'll mark the ground where the tripod feet rest! #astronomy #telescope #meadeinstruments

The 6-Inch Meade all set up for Tonight

LATER THAT NIGHT: How did it go? Pretty well. The scope worked great but the operator.... let's just say that it's pretty important to tell the telescope control system what the current MONTH is if you want it to point the telescope accurately! If you enter "June" as the month when it's actually April, you're in for plenty of frustration! I missed that simple data point several times. Ugh! Once manually aligned, the scope found objects pretty accurately without precise polar alignment. Through light-polluted, hazy cloudiness, I observed Jupiter with Io emerging from behind, saw the beautiful stars of M44 - the Beehive Cluster," saw the Hercules Cluster - M13 - as a fuzzball (no individual stars), and experimented with several eyepieces. I need a couple of really good eyepieces. Finished up around midnight, tore down and stowed the scope. Now it's off to bed!
