This is my first attempt of M51 the 'Whirlpool Galaxy', and also the first time using my new mount & scope (SkyWatcher EQ6-R Pro and SkyWatcher ED80 DS-Pro). Polar alignment with QHY Polemaster wasn't perfect (when I did the axis rotation I couldn't get the chosen star to exactly on the green circle) and I haven't got a field flattener yet, waiting for that to arrive.
I managed to get 80 x 3 minute lights unguided with my Canon 2000D at prime focus with Optolong L-Pro Broadband light pollution filter, 20 x darks, 40 x bias, 36 x flats and 40 x dark flats, stacked in DSS and processing in photoshop. Total exposure 4 hours.
I cropped the image slightly as I had a horrible dark and grainy gradient on one side of the image when stretching, but couldn't crop too much either or it became too pixelated.
Hope you like.
