Description

This is my first mosaic, it is a three panel mosaic of Messier 31. Here is the panel breakdown:

106 subs - left\top panel
110 subs - center panel
107 subs - right\bottom panel

All subs but 10 for the center are 10 minute exposures. I did 10 of the center at 30 seconds for core. Would have like more shorter exposures for core but enough is enough. :-)
