Description

M51, shot with the Orion G21 Color camera. I've since learned to take a lot more dark and bias frames.

This was also using the AP900 with the very old CP2 motor controller. Right after this I upgraded to the CP4 with APCC Pro, and the mount/sky modeling system in APCC really improves the tracking/goto accuracy.
