M37 (NGC-2099)

Open Cluster

Auriga

                                                                                                     

 

M37 is the most spectacular of the three open clusters in the constellation of Auriga and contains 1890 stars spread across a region of 20 light-years, at a distance of 4,400 light-years from Earth.  The brilliant orange star near the center is the brightest of about a dozen "red giants" in the cluster, whose visual orange-red color contrasts with the surrounding young blue-white stars when viewed thru my 4" refractor.
