M 37

Messier (M) 37  is the brightest and richest open cluster in the constellation Auriga at a distance of 4.500 light-years. It was discovered by the Italian astronomer Giovanni Battista Hodierna before 1654. M37 is located opposite from the Galactic Center as seen from Earth, so the cluster is located in one of the nearby outer arms. Estimates of its age range from 347 million to 550 million years. The cluster has 1.500 solar masses and contains over 500 identified stars. 

My first image was obtained in 2018 using a Canon DSLR, then, using the ASI1600MMpro, 8 years later in 2026.
