Unfortunately we were mostly clouded out for the star party. From the sounds of it some of the other big star parties going on concurrently were also clouded out. It just wasn’t a good weather weekend for a large portion of the eastern US. Regardless of the clouds, the rangers at Pickett put together some good food and speakers for the event to keep it entertaining. I stayed for only one night and snapped a few pics of the hazy skies with the Milky Way trying to peak through.
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.

Just Some Slightly Concerning Weather Passing Through
Everything is buttoned up and locked down. Luckily it skirted us to the North.

A couple images from last years 2017 CSSP that I finally got around to looking at. It wasn’t a very productive astrophotography trip but enjoyable none the less.
If you’re going to come to a star party like this please follow the rules and don’t be a rude jackass like the following guy. We all understand and tolerate some light issues, car alarms, and emergencies but when you light the place up over and over without any regard for your neighbors I would suggest staying home and not ruining everyone else’s vacation!
I recently replaced the dome control electronics after the Foster Systems controller bit the dust and I replaced with a MaxDome II controller for rotation and shutter operation. It’s working flawlessly so far and I couldn’t be happier. I threw the 5″ refractor back in the observatory with the 16803 chipped camera for a widefield rig at 2.2 arcsec/pixel resolution. Drizzle processing yields better star shapes/sampling than the low resolution would suggest. Both images are cropped from the same image with 20.5 hours of total exposure time in the traditional Hubble Pallet.
I was the first one to arrive for the star party on Saturday night at Look Rock South. It’s a beautiful view to the south looking into the Smokies.
We definitely had some clouds for the beginning of the night with some sucker holes now and then. I was never able to get off a 20 minute shot without the clouds rushing in within 10 minutes…
But things finally started to clear up and the Milky Way really started to pop out.

Once it was cleared up I was off to take some test shots and validate the portable rig was ready for more serious projects. NGC 6820 AKA Sharpless SH 2-86 and all the surrounding emission and dark nebula has always been a favorite of mine. It’s located in Vulpecula not that far from M27, the Dumbbell Nebula. It reminds me of a less popular M16 with it’s gas and dust pillars and dark globules. Open cluster NGC 6823 resides in the midst of the nebula and is about 6,000 light years away.
I’ve got multiple items across our home, garage, and the observatory which suffered from a local discharge on 7/6. The observatory was the worst hit with the computer, mount, 2 ethernet switches, powerline ethernet adapters, weather monitor, and possibly other items damaged.
Work continues to repair, replace, and rebuild. Unfortunately, I think I’ll be down for a little while as I continue to evaluate the extent of the damage. Hope to be back up in time for some summer nebula imaging but not holding my breath.
Getting ready for the eclipse and testing one of the imaging setups today. Took a single DSLR shot of a couple sunspots. Sun spot 2648 is on the left, 2645 is the most prominent group closer to center, with 2644 on the right.

NGC 206 is the brightest star cloud in the arms of the Andromeda Galaxy visible to us here on Earth. You often see M31 imaged wide field but there is a wealth of detail to be found in the star clouds and dust lanes that start to pop out with a little more focal length. Taken late last year from my back yard.

We’re in Galaxy Season and without the 10″ RC I’ve instead focused on the 5″ refractor with a small pixel size camera to squeeze out some detail. Imaged from the backyard observatory in ~20.5 mag/arcsec^2 skies.

Cloudy winter nights have inspired a second look back at some fun summer targets. Here’s NGC 6871 in Cygnus.
