4/26/2019 Globular Cluster M3

Here’s a picture of Messier 3 (M3) in the constellation of Canes Venatici. Taken last night with my 11″ SCT set at f/6.3 at the River Ridge Observatory. If you are familiar with the stars Arcturus (4th brightest in the sky) and Cor Caroli (Alpha Canes Venatici) this lies almost exactly halfway between them and is an easy target with binoculars. M3 is a globular cluster of about 500,000 stars about 34,000 light years from here.
Come to National Astronomy Day at Pinnacle Mountain State Park on May 11 and you might see it for yourself. Click on the image to see it full size.
