Three nights with generally good conditions with the seemingly always present wildfire smoke.
TBD on some widefield DSLR shots
We had four relatively clear nights in a row. Some didn’t start great but all four produced usable imaging time even if the nights aren’t much more than 4 hours of astronomical darkness this time of year.
A couple shots with the Canon 6D DSLR and a Rokinon 135mm wide open at f/2.

I attended the annual Calhoun County Park Star Party (Oct 5-7) for the first time this year. The sky wasn’t the best it could be. Friday and Sat night both had humidity and dew off the charts with variable fog that seemed to slide up and down the hill but never got so high that it killed observing. I can’t help but think that it impaired the images a little but it may have just been the choice of a faint target during a hazy time of year. Sky quality measurements topped and held pretty steady around 21.6 mag/arcsec^2. I’m sure on a crisp night it would be a little darker. While there were some small light domes on the horizon they weren’t hardly worth mentioning in my opinion. The park was wonderful and the staff was so friendly they even prepared a great meal for us on Sat night. In total about 16 people showed for the party from TN, WV, PA, OH, and KY. Special thanks to Larry McHenry for posting info about the star party and turning us onto this event and Calhoun as an observing site. He typically posts updates on Cloudynights star party forum for upcoming Calhoun events.
Since Calhoun is pretty dark I decided to go after a fainter full spectrum object than I could ever do from home. VdB objects (reflection nebulae compiled by Sidney van den Bergh) are great targets when looking for something off the beaten path but aren’t always what I would call showcase objects. VdB 14 and 15 make for a nice parring here in a rich park of the sky in Camelopardalis.
I made the 13 hour trip up to Cherry Springs State Park for the Annual CSSP Star Party hosted by the Astronomical Society of Harrisburg PA, Inc. I went up a few days before the star party since it’s always helpful to get a good spot. Those of us that were there early on Monday night were treated to a fabulous night with SQM measurements >21.9! Overall it was an amazing streak of clear weather for PA with a total of 4 imaging nights. I was hoping for one or two so as not to set my expectations too high so I was very pleased with four nights!
I even did a little visual at low power with a 4″ refractor. LDN 1795 (large 50’x50’dark nebula in Scorpius) looked absolutely amazing to me at 19X. First time I had a WOW moment visually.
