 all, most, or even just a few of the Messier objects, it may be time for you to participate in a Messier marathon &mdash; trying to see as many Messier objects as you can in a single night. I remember participating in Messier marathons in the early 1970s. In 1974, from the reasonably well-lit campus of the Ohio State University in Columbus, Ohio, a friend and I logged 106 Messier objects in one night using his 6-inch Newtonian reflector. Since then, I've seen all 110 in one night more than a dozen times.<b
