Re: Terry's Astronomy Thread.
What's in the Sky Tonight?
March 21, 2012
-The moon is out of the sky long enough to do some serious deep sky hunting. Have you heard of the messier objects? Messier was a comet hunter who generated a list of objects that were -not- comets, and passed this list on to other comet hunters. This list generated 110 objects, and is mostly galaxies, with a fair amount of star clusters. Some nebulae exist too. Refer to here for the complete list of Messier's catalogue.

Star parties are one of the best ways to explore the deep night sky. Red light is used to ensure that night vision is not ruined, as to see the contents of this image requires 20 minutes of absolute darkness, and only red light seems to keep that vision. This particular photo was taken during the 10th annual Iran Messier Marathon in April 2011. A Messier Marathon is completed when one views all 110 of the messier catalogue in one night. The stars rise and set fast, especially when you're searching for 110 different objects, some of which only being visible for about 20 minutes before they set! How many Messier objects do YOU see? hint: the green laser points to M8.
