Description

If you have a large screen, I recommend viewing Revision C to get the full span of background galaxies in the field. Rev D is an annotated version of rev C that shows objects of interest, including a brown dwarf candidate. View "Final" Rev E if you are mostly just interesting in the larger galaxies. I have removed the original versions, A and B, which had much to dark a black point.

I had finished capture images of nearby NGC 6239 in Hercules for the evening and noticed this pair of galaxies nearby on the sky chart and thought I would have a look. It turned out to be a really interesting pair of interacting galaxies and decided to take a deep dive on it with a bunch of exposures, and then another batch a few nights later to help draw out the gravitational tails and fans in UGC 10610 (the larger of the two galaxies, the smaller is MCG+07-35-005).

UGC 10610 is a barred spiral has a redshift of z=0.03365, putting it and presumably MCG+07-35-005 at about 460 million light years (assuming a Hubble constant of near 70). This makes UGC 10610 pretty spead out, given its angular size, making it roughly 250,000 light years across in its longest dimension from one end to the other of its tidally distorted arms. MCG+07-35-005 is a lot smaller at only 83,000 light years in diameter. MCG+07-35-005 appears to be spiral with a ring of intense star formation near its outer edge, no doubt due to its interactions with UGC 10610.

The rest of the mid-sized spirals in the field are much more distant, given their size and brightness, being between roughly 500 mly and 1 billion light years away. The rest of the hundreds of faint smudges (anything blurry at all is a galaxy), many clearly grouped into several clusters across the image, are several billion light years away.

Each of the 18 subs 8 minute were a live-stack of 320 x 1.5 second exposures in SharpCap, which I then stacked and processed in FitsWork 4.
