Observing is the
Heart of Amateur Astronomy
In 1781, French astronomer Charles Messier listed 110 of the most
important objects available to amateur observers
and their telescopes. As a member of the AAAA, you are eligible to earn the Astronomical League's Messier Observing
Award for observing all of the beautiful objects on Messier’s list, get an official Certificate of Participation, and receive a Messier Club lapel pin. There are other programs you can participate in, too, including ones for binoculars,
telescopes, and computers. See the list for all the observing programs available to Astronomical
Legue members. We have
an observing club to meet every individual's interest in this wonderful hobby of ours.
You MUST be a member of the Astronomical League, either through membership in an affiliated
astronomical society or as a Member-at-Large, to receive certification for AL Observing Programs.
