M25 and M73 - the Messier that almost wasn't!

M25 is an open cluster in the constellation Sagittarius and located some 2,000 light-years away (source: wikipedia).  M73 is an asterism (group of stars that appear close to each other from earth) in the constellation Aquarius and located located 2,500 light-years from Earth. Messier described the object as a cluster of four stars with some nebulosity, however, no one since then has observed it (source: wikipedia).  Of course I would have liked to have longer exposure but M25 went behind a tree and I was entertaining an out of town guest (brother) during the session.

These two objects represent 40 and 41 on the Messier Objects with an ED80 project that I am working on.
