Description

NGC is  lovely little Sbc spiral galaxy sitting 45 Mly away. Better seeing allowed for some reasonable detail to be resolved.

My galaxy season tour continues as I assess methods used to control fixed pattern noise and the effects of RBI for the Aluma AC4040. This image was acquired on High StackPro mode with 60s camera stack frames.
