Description

NGC4565 shot during 3 nights in April and May. I found out (when it was too late) that the frames made in April had a different rotation. When processing the data I decided to use all the frames, so I had to crop a large section of the total stack. In total over 9 hours of data. This is the first time I used an exposure time of 5 minuten instead of the usual 10 minutes. This galaxy doesn't have faint structures so I could use the same time for double the amount of exposures, thus creating a better SNR. This is a LRGB-combination (37xL 29xR 23xG and 20xB).
