I have finally managed to photograph a recognisable galaxy. I used a Canon 700D (which I am borrowing) set to ISO 6400 and 23 second exposures. Unfortunately, I was only able to take 30 photos before it went out of my field of view. DeepSkyStacker allowed me to stack 26 photos. I also took flats, darks and bias frames. I used ISO 6400 because I have a Skywatcher EQ3-2 tripod which gives me errors after 90 seconds or so, although it sometimes messes up at 1 minute.

This is something that I never thought would be possible by me. So, it feels wonderful to be able to photograph it. I know that I need to take more lights to reduce the noise produced by using such a high ISO.

Thanks for looking.

Fantastic work! Grerat capture and composition!!!

When you say the tracking messes up, what do you mean? Are you using PHD and it starts beeping and flashing red? I used to only be able to track for 60-90 seconds myself. Turned out my balance was way off and lop sided.

When I swapped out the mounting plate for a longer one and balanced it perfectly I then managed 10min plus subs! Longer if it weren't for light pollution.
