M3 or Messier 3 is a globular cluster in Canes Venatici. It is best seen in May in the northern hemisphere. It is 34,000 light years away and is magnitude 6.2. There are no bright stars near it to allow star hopping but it is just about half way between Cor Caroli and Arcturus. In this video I'll show you how to find it and I'll give you some observing tips and show you what it looks like in binoculars, small telescope, and medium telescope-- a Dobsonian Telescope and a Schmidt-Cassegrain Telescope.
