Description

This is 35 minutes of data (forgot to mention each image of the 4 images combined here was a SharpCap live-stack of several hundred 1.5 second images to produce 3 10 minute images and one 5 minute image) gathered in my backyard on a pair of galaxies from the very much neglected UGC catalog. In my opinion they are worthy of inclusion in the Arp Catalog, but didn't make the cut, I guess. The face on bright SBc-type barred spiral with disconnected arms on the left is UGC 12075, while the beautifully symmetrical near edge-on galaxy more toward the center of the field is UGC 12073. The UGC 12075 face-on galaxy also seems to be interacting with another tiny galaxy, PGC 214848 above it (almost hidden behind a star) and to its left, PGC 69117, which appears to itself be an interacting pair of galaxies. The near edge-on UGC 12073's listing in the Simbad database indicates that this is an SBc barred spiral too, but the image here shows no sign of bar as far as I can tell. I think its more likely an unbarred spiral of between type Sb and Sc, since you can see the arms wind all the way in to what appears to be a central bright disk, not a bar.

The designations starting from far left to right are:

PGC 69127 (the bright diffuse 15.4 magnitude face on spiral)

PGC 69117 (The fan shaped interacting pair at 15.6 magnitude)

UGC 12075 (the face on barred spiral, 15.0 magnitude)

PGC 214848 (17.7 magnitude, above UGC 2075)

UGC 12073 (the near edge on 14.9 magnitude spiral)

PGC 69081, at the far right, hiding behind a bright blue star!

That last one, PGC 69081, looks like a barred spiral with the arms forming a bright blue ring of intense star formation. The rest of the fainter galaxies don't seem to yet have been assigned any designation.

This whole region has faint red and blue nebulosity (including Sh2-126), which shows up as faint color noise and variations in the blackness of the sky in this image. Its just too faint to pick up from my backyard with the light pollution gradient I have to remove. At some point in the future, I'll get some more data on this from a dark sky site to try and capture this background nebulosity.
