General Motors Astronomy Club

About Us

The General Motors Astronomy Club (GMAC) is a non-profit organization of people dedicated to sharing the night sky with others. The club hosts monthly events at the General Motors Milford Proving Ground, as well as sidewalk astronomy events in downtown Milford and other locations in Southeast Michigan. Founded in 2017, our club is still growing and always looking for new members. We appreciate our member support, but you don’t have to join the club to enjoy the night sky with us. Most of our events are FREE and open to the public, and no equipment is required to participate.
