The M33 galaxy - Our 2nd big neighbour

A galaxy that I haven't really imaged before due to my fears that it might be too faint for my light polluted location. And indeed the outer edges of the galaxy are extremely faint. But a painful processing session and lots of integration time made for an okay image in the end!
