M 39 is a large, scattered cluster of stars in Cygnus, about 12 degrees east and 2 degrees north of the bright star Deneb. The brightest members of the cluster are blue B and A type main sequence stars. Fairly low magnification with the telescope will give the best view. The surrounding area is rich in faint stars and is a wonderful region for low magnification sweeping.
