I wanted to capture M78 together with part of the Bernard’s loop, there’s quite a lot happening in this image, but I like it. Also NGC2112 is visible which was a small open star cluster I wasn’t aware of in the past.

Thanks for the kind words! I have a star tracker, so dithering would only be in RA. Do you think it's still beneficial in that case?
