How did you know that?

I was checking out M17 & M16 the other night for the first time in I dont
remember how long. You can easily forget in the pursuit of other things to
go back and look over what you have already seen. I must of spent a couple
of hours marveling at them, wondering why I hadn't come back sooner. Infact
I'm about to head out and check out M1 another I haven't in awhile. Mars is
looking good too, not quite good enough to image though
