I managed to get 45 mins usable of NGC4945 on Tuesday night. I'm quite happy given it was damn near full moon. There's still an appreciable gradient in the image, but I'll live with it! 9x5min subs, ISO 800; 10" Meade SCT at f/10; Canon EOS 60Da.
Nice indeed some good detail in there, even considering the conditions of an almost full moon and at F10 thats a ripper of an image. Notice you captured another galaxy in the bottom left northern end disgnated 0219-025. Cant find much on it at the present.
