M101, the Pinwheel Galaxy

This is a reprocess of an earlier image using Generalized Hyperbolic Stretch. For this image I collected 45 light frames and used 12 dark frames from a previous session. Also took 35 flat frames and used a master superbias for calibration. The pre and post processing was done in PixInsight.
