These are two open clusters bathed in the Milky Way near the boundary on Cygnus. Uncountable fine Milky Way stars surround the clusters.
NGC7209 is positioned about 6 degrees east of M39, an open cluster in Cygnus. The cluster contains about 25 members and 25 arc minutes in diameter. You can clearly enjoy the strained S-shaped star chain through small scopes.
Another open cluster of NGC7243 is lying 4 degrees NNE of NGC7209. This pair looks very same except that NGC7243 has a little bit smaller size than NGC7209. The cluster shows us like a triangle only with binoculars.
