[edit] Background

In real astronomy, the brightest star in the Cygnus group is referred to correctly as Alpha Cygni. It isn't known if this was the intention of the writers to refer to that system, but on uncertainty exists that makes that supposition difficult: Alpha Cygni is also known as Deneb, and that system has been visited several times in Star Trek. It is possible that the "Alpha Cygnus" name is an overly formal manner of referring to Deneb, and the systems are intended to be one and the same, but it has also been pointed out that the familiar Deneb planets referenced might belong in another system named Deneb or that Alpha Cygnus and Alpha Cygni are separate entities that share a common naming convention due to unknown reasons.
