Description

M51 at 2000mm focal length unguided on the AP1100, using a dec arc tracking model.  Seeing conditions were better than average for my location for a few days, leading to decent resolution in the spiral arms. This was also a good image to practice using the Generalized Hyperbolic Stretch process in PixInsight.

LRGB, using a super luminance (combining the RGB and Lum masters into a single luminance image), imaged over three nights.
