The objects in the Messier catalog that are the farthest south are two star clusters. M6 is also called the Butterfly Cluster and M7 is also known Ptolemy's Cluster. They're splendid objects seen in their glory in the southern skies, but if you live in the far north you can't see them at all. Ptolemy and the Butterfly – M7 and M6

Ptolemy's Cluster (M7) imaged by ESO's La Silla Observatory in Chile. It's one of the most prominent star clusters in the sky, easy to spot if you're looking in the direction of the tail of Scorpius. Credit: European Southern Observatory (ESO)

Here's a glorious picture of M6 the Butterfly Cluster. This doesn't look like a butterfly to me. However when a saw a thumbnail of it, it was rather butterfly-like, so I guess that's the trick. Copyright: F. Espenak
