M29 is a small open cluster found at about 2 degrees south of Sadr, γ Cygni. The cluster is fairly modest for registered in the Messier's catalogue; not suitable for binoculars. You can detect four bright stars forming a tiny rectangle and some other members are surrounding with a magnifying power of about 30 or so.
Actually, this field has a fine gaseous region of IC1318, and a fluffy nebula surrounds M29 itself.
