I'll side with Joe. Those who did catch M74 that night saw very very
little of this glorious galaxy and had to take anything they could get.
If there was a blazer actually in M74 serving as a handy marker, that
would be considered the luck of the draw and a lot more could have and
would have checked that one off. M74 is a fine object in its own right.
I hope the many Marathoners do eventually get a good look at it higher
in the sky some time rather than the usual dismal view at the horizon.
