In June 1970, I spotted globular star cluster M3 in Canes Venatici the Hunting Dogs with my new 4½-inch Tasco reflector. That night, fair-weather clouds studded the sky. My guide stars, Beta (β) Comae Berenices and Eta (η) Boötis, blinked in and out of view with frustrating irregularity. No matter, I pointed the finder’s cross hairs at the cluster’s position and waited for a hole between the clouds. When one appeared, I swept the scope madly about until — bam!
— I caught sight of M3’s fuzzy glow near a 6th-magnitude star.
