Description

m31 112 unguided subs with a modded canon 600d with an Astronomik CLS EOS clip filter, a Canon 70 200 f4 lens on top of a Ioptron Smart EQ. Image risulted slightely out of focus, even if I have checked it carefully before starting imaging. I had to bin 2 the image in order to reduce stars diameter. Stacking with DSS and processing with PS. Thanks for looking.
