HOW TO FIND IT:
This one is easier to find with the wide field of a pair of binoculars than with the smaller field of view of a telescope. With binoculars, scan the area between Alpha Canum Venaticorum, also called Cor Caroli, and Arcturus.
WHAT TO LOOK FOR:
Some may regard this as the best example of a globular cluster in the northern skies.
M3 should look very round and bright, breaking up into dim individual stars on its edges.
