The Pinwheel Galaxy, M101

M101 is central in the frame with NGC 5422 at the top left, the distorted dwarf spiral galaxy, NGC 5474, bottom right, and NGC 5477 on the left hand side (8-o'clock position).

I collected a total of 205 x 30s subs at ISO1600 on 25th March 2017, from which I selected 147 to stack in AstroArt. I used 60 flats and a generic bias from 200 frames. Processing was performed in StarTools and final polishing in both Lightroom and PWPro.

Equipment:  Fuji X-T1 through an Altair 102mm f/7 Super ED with a TS Photoline 2" 0.79x reducer/flattener. Mounted on a Nexstar 6/8SE Alt-Az mount, now withStarSense.
