M3 in Canes Venatici

Messier 3 is one of the bigger, brighter globular clusters found in the sky's northern hemisphere (the very best ones are in the southern hemisphere). Summer is the main season of globular clusters, but M3 serves as a springtime harbinger of these sparkling globes of thousands of stars.

This was made with my 92mm refractor from about 30 5-minute exposures using a ZWO ASI294MC Pro camera. My site was in the Mojave Desert with a Bortle Scale number of about 3.
