Description

A simple tracking mount and a decent lens on a decent camera can do wonderful things, as everybody knows. Just letting it run for a couple of nights, and I was surprised to find 730 subframes on the SD card. Of course the goal was to feature the dust and weak nebula filling the field just around the popular couple M81/82, but distilling the data into a nice and clean looking picture was a nice pile of processing steps too.

As it happened, just at that time Comet Atlas passed the field before it broke apart. Its the green dot at right, almost "lost in transition" before the background of deep and deeper sky objects.

See here a small video showing its movement during the exposure sessions:
