Leo Triplet (M65, M66, NGC 3628)
Leo Triplet: Galaxies Messier 66, 65, NGC 3628 and others. On a properly calibrated monitor a very faint tidal tail can be seen to the left of NGC 3628 (the bar shaped galaxy on top). Despite the long integration time the tail is hard to make out. My optical system can't do much better than this.
