I decided to look at some deep-sky objects in Sagittarius. When I turned to M70, I saw a fuzzy object in the same field, and almost immediately suspected a comet, since I had been looking at M70 last month, and knew there wasn't any other objects there.

I love the irony - I've spent over 400 hours of my life looking for comets, and haven't found anything, and now, suddenly, when I'm not looking for one, I get one dumped in my lap.
