Description

It's been quite some time since I've imaged M31. This was also a test of my mount and was done unguided, except for the long Ha exposures. I had some problems with the red and could only use half of my subframes. Processed in PI with 2x drizzle. The last time I imaged this was with a Canon 550D DSLR.
