This small cluster is about 1/3 the distance between Delta and Beta Cygni.
The cluster is rather compact, and at 49X with direct vision, it appears as
an oblong smudge; using averted vision brings out several individual stars.
The more magnification you use, the better the cluster appears as more and
more stars become visible.
At 122X, the cluster resembles the letter W. It contains two not-quite-parallel
lines of stars. Between them, at the closer end, are several more clumps of
stars. At 188X, about 20-25 stars are visible, mainly grouping in pairs and 
triples. 305X revealed a few more stars, but didn't really improve the view
