I used a modded Canon EOS 700D and a WilliamOptics ZS71 ED on a HEQ5 with belt mod to take this pic of M 33. I wanted to take 60 images of 3 minutes each but due to DSLR connection problems (not a complaint, just a statement) I only got 22. Plus my flats were taken wrong (my bad, I used a too short exposure) so I had to retake tonight them which introduced some artifacts in the background because I already moved the telescope with the camera attached though I didn't touch the focuser. Thus I needed to suppress the background a lot leading to some haze around the bright stars due to the mask used.
Nevertheless it is a result that I am very content with, to say the least. All stacking and post-processing was done in PixInsight.
Actually I am trying to move away from PI for stacking. Recently I bought a license for Astro Pixel Processor (APP) which has a much simpler workflow than PI and superb results. I didn't use it this time since it gave bad results because of the flats. But I made a North America and Pelican mosaic that I will post here next and I used APP for stacking and then PI for post-processing since I don't have PhotoShop.
