It's a compact spiral galaxy about 2 degrees west from zeta Cygni, a tip star of Swan's wing. The galaxy is unfamiliar but has fairly large scale of 5 arc minutes in long axis. And we can detect detailed structures of central nucleus and surrounding dimmed part. This field is equivalent to eastern edge of summer's Milky Way, there're uncountable fine stars.
