M31

M31 from the 30th Oct, 28×2.5min exposures plus flats, darks and bias frames. Stacked calibrated and processed in pixinsight. Unfortunately i messed up the flats as a piece of unfocused dust moved in between taking the lights and flats. I solved this by usingĀ  clone stamp in pixinsight. This is a lesson i guess- I should take the flats at exactly the same time as the lights and not leave it 24hrs at the same focus point.
