Last year (2014) I was conducting some mosaic tests for future projects.  I attempted a widefield 9 panel mosaic in Cygnus and processed the hydrogen alpha data but never got around to completing the tri-color Hubble Pallet image until now due to some difficult to process issues in the O[III] and S[II] channels.  Those difficulties, combined with the fact that I only gathered about one frame of each channel per panel in the mosaic (very thin data!), meant that I wasn’t exactly thrilled to process this one to completion.  Time away from the hobby due to the out of state relocation though has made me a little anxious to get back to imaging so I decided to revisit some of this forgotten data.

Cygnus Mosaic Cropped & Reduced to 50% Size. 9 Panels, 1x20min per Ha, O[III], S[II] Channel per panel. Total Time 9 hours. Taken with an Apogee U16M and Tak FSQ-106ED.

I began work on a tri-color Hubble Pallet image during the summer of 2014 but due to weather and other obligations did not capture much in the way of Oxygen [O III] and Sulfur [S II] emission data for the mosaic project so am leaving it as a monochrome image using only the Hydrogen Alpha emission line data.

Cherry Springs

Cherry Springs

Monday night was my first visit to a dark site; or at least my first visit since catching the astronomy bug.  Upon arriving at Cherry Springs after the 4 hour drive I noticed there were quite a few people  still hanging around after the Black Forest Star Party which was held over the weekend.  According to some of the other amateur astronomers, the weekend star party was a bust.

We found a vacant spot to setup our tents right next to one of the RV style power outlet posts scattered throughout the observing fields.  I can’t stress how wonderful it is to have power provided  on the field for the astrophotographically inclined!

The grounds were well kept and the main bathrooms much nicer than expected.  The surrounding area is gorgeous for anyone who enjoys the outdoors.

As nice as the park was, the show obviously didn’t start until the sun went down.  The Milky Way was more prominent before astronomical twilight than I’m used to seeing here in the PGH region after astronomical twilight; even at the Greene County site.  By 10:00pm it was gorgeous and I snapped a quick 3o second shot on a tripod and marveled that the dark lanes extending out from the Rho Ophiuchi / Antares region were clearly visible in a short exposure so close to the horizon.

Seeing the sky like this puts everything in a different perspective.

Yes, it’s depressing being back in light polluted Pittsburgh but I’m really glad I finally made it out to Cherry Springs after all this time.

I had plans to shoot some other objects but due to poor planning and setup of my tent I couldn’t take some of the deep southern objects I was hoping for.  I settled for 5.5 hours of exposure time on NGC 7023:  The Iris Nebula.  I have shot the Iris before but was never totally happy.  I’m still not quite satisfied but it’s certainly better than what I’ve gotten around here.

The Iris Nebula, also NGC 7023 and Caldwell 4, is a bright reflection nebula and Caldwell object in the constellation Cepheus. NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +7 star, SAO 19158.[1] It shines at magnitude +6.8. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across.[2]

It’s that time of year when Cygnus rises high over head and displays a multitude of nebulous treasure.  This mosaic is only a portion of the Cygnus constellation but represents a large patch of sky almost 9 x 9 degrees.  This is only a test framing as I create a game plan for a summer long imaging project.  For a sense of scale, I have included a gibbous moon which was not part of the original image as well as a full scale crop of the Crescent Nebula, bottom right, to show the full size scale of the original 83 megapixel image.
