NGC 1039 (M34)

5. NGC 1039 (M34) Open Cluster Open cluster M34 can quite easily be found (even with the naked eye under good conditions) as it lies just north of the line from Algol (Beta Persei) to Gamma Andromedae. In small rich-field telescopes M34 appears as a fine sprinkling of stars, but larger instruments make it a much more rewarding object. Depending on the aperture used, the diameter of this open cluster will vary from 15' to 30'.
