Deer Lick Group and Stephan’s Quintet

This was one of those projects where nothing was going to go right. Between dew problems on my primary mirror, un-forecast clouds, and Windows deciding to update right after I started imaging and went to bed, three nights turned into barely 12 hours of data. And the flats didn’t work at all with the dewing and skyglow. I decided to just go with what I had and hope to fix the dew problems for the next target.

The Deer Lick is the large galaxy to the right, with four smaller “flea” galaxies to the bottom and right. The fleas are between 300 to 380 million light years away. To the left is Stephan’s Quintet, four interacting galaxies that lie around 210 to 340 million light years away, with a foreground galaxy only 40 million light years away.

Here is a comparison of what I got last year with a DSLR and my dobsonian.
