This trip to Cherry Springs State Park promised an amazing clear stretch but was marred by dense smoke obscuring much of the sky from the wildfires raging in CA and other parts of the US.
The sun looked like a planet hanging in an overcast sky due to all the smoke. If there had been any sun spots they may have been naked eye visible without a sun filter!The sky was clear yet the blue wasn’t quite able to break through the hazy smoke.Frank in the Astro TentThis is what dealing with the public usually looks like 🙂LDN 1235 – The Dark Shark FSQ-106ED with SX-46 CCD on AP900GTO Mount Only salvaged image during the few smoke free nights

Road to the Observing Ridge at Dawn Thursday Morning
After missing the BFSP at Cherry Springs State Park, PA last new moon we were anxious to get out for one last hurah for the year. Weather looked great initially from midweek into the weekend but rapidly went downhill as we got closer to the weekend. We did however have an amazingly clear Weds night and clear until 3:00am or so on Thursday.
Observers on the Ridge on Thursday Morning
Friday morning arrived with clouds and slightly warmer temps (no frost) than Thursday morning. The sunrise was spectacular.
I am not a galaxy imager. I’m at home with short refractors imaging large nebula in our own galaxy. Spring and Fall are more or less galaxy season though if you want to be able to image the same object the majority of these longer nights. So I picked out a decent size bright galaxy and dusted off the long f/ratio 5″ refractor and gave it a try. It’s not without it’s problems but nice to see a 28 year old refractor still collecting photons!

We had some great weather for the annual star party at Pickett State Park, TN last new moon. This star party is still young and looking to grow. The park rangers are doing a great job, it’s a great venue for presentations and a great field for observing / photography. I’m not sure why it still remains a hidden gem of sorts.
Overall sky quality, other than some early clouds, was excellent. With SQM measurements around 21.77 mag/arcsec^2 this was the darkest I’ve seen Pickett. I would note too that of the other dark sky sites I routinely visit, this quality of night is nothing to complain about.

Image scale of 2.33 arcsec/pixel. Exposure time ~13.5 hours. Also plainly visible on the right edge of the frame is SH2-155 The Cave Nebula. Sometimes the faint objects like 154 don’t get a lot of love because they’re not much to look at. At least it’s got a nice tight open cluster NGC 7419 nearby to draw some attention.Annotated
With weather looking wet and wild for the 2019 Cherry Springs Star Party and things looking slightly less soggy at Calhoun we decided to cancel on Cherry Springs and gamble on Calhoun. Good thing we were setup on the top of a ridge so we never had to deal with muddy conditions considering all the rain we didn’t know was coming.
The first couple days were all clouded out.Night time conditions were very soupyCouple nights later things were improving but still very humid and hazy. The Milky Way was at least starting to pull out of the haze.Cloudy rainy days Equipment setup and hoping for clearingFrank and the Astro TentFinally some stars poking through the clouds.

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.
