Observing podcast: Cor Caroli, the Pearl Cluster, and the Leo Triplet
May 6-13, 2010: Cor Caroli is a nice target for beginners, while the Pearl Cluster and the Leo Triplet provide nice targets for telescope owners.
May 6, 2010
Each week, Astronomy magazine Senior Editor Michael Bakich, a master at explaining how to observe, posts a podcast about three objects or events you can see in the sky.
Cor Caroli (Alpha [α] Canum Venaticorum) is the brightest star in the northern constellation Canes Venatici the Hunting Dogs. It shines at magnitude 2.8, but the constellation it belongs to is faint. So, just look 17.5° due south of Alioth (Epsilon [ε] Ursae Majoris) in the Big Dipper's handle.

In each episode, Michael highlights:
- One object you can see without any optical aid
- One object you can see with a small (4-inch) telescope
- One object you can see with at least an 8-inch telescope
