Description

With this picture I tried to show the very weak outmost spiral arms of the galaxy. I have used the camera in binning 2x2 mode to significantly increase the amount of the collected light.

When checking out my picture I found a barely visible dot, marked low right, which is a galaxy with a magnitude of 20.1, my personal record. However I didn't find a redsift value for this. May be there is even more.

Clear sky!
