The Aldrich Astronomical Society, Inc. was established in 1932 and is a central Massachusetts based 501 C (3) Non-Profit Organization of amateur astronomers who have united to promote an understanding of the Night Sky through their mutual interest in observational astronomy (stargazing) and telescope-making. The Aldrich Astronomical Society, Inc. is pleased to be working in collaboration with the Cornerstones of Science, who are based in Brunswick, Maine to support the Library Telescope Program.  This program enables interested libraries throughout Massachusetts and some surrounding states, to acquire a loaner telescope for their library patrons.
