M 52 is a small but bright open cluster in Cassiopeia. Being rather small, it is a very good cluster for the telescope.

45 minutes exposure, Kodak Elite 200 slide film.
5" f/5 refractor at prime focus.

To the west (right) of M 52 is the emission nebula NGC 7635. Sky Atlas 2000 mistakenly indicates this object as a planetary nebula. It is however, an extremely hot, young, massive star that is losing mass. The more common name for the nebula is the Bubble Nebula. To the upper right is another emission nebula, NGC 7538.
