Data: mag 6.9  size 12.0'
Position: RA 23:24.2  DEC +61:35
Description:
188X is about the most power I can use and still keep it entirely within the field of view. The open cluster has a bright star near one end. The other stars are all at least one magnitude fainter. On the opposite end of the cluster, there's a straight little string of 10-12 stars running parallel to the bright star.

The cluster is generally round in shape, with 40-50 stars visible. 81X offers a nice overview of the cluster, nicely framed in the eyepiece.
