Messier Challenge - M3 Globular Cluster

M3 in Canes Venatici 22nd March 2020 @ 02:08 UT

A compact ball of glistening stars formed before my eyes as frames stacked upon frames.
M3 - Canes Venatici

Globular clusters are amazing sites visually, so I was not disappointed by the view I got of M3 using my EAA setup.
