Description

Another galaxy from my backyard since I was encouraged by the result of my M51 from the suburb of a big city. Didn't turn out too badly given that the transparency wasn't good one of the nights and there was a quarter moon out a couple of nights. Clear nights are so hard to come by these past few months.

Description: This revision contains a few more hours of data from the city as well as about 2 more hours of luminance from a dark site. I processed it to reveal more of the fainter stuff. But is it better than the original?
