| Notes: | Berkeley 81 is the object to the left that *looks* like an Open Cluster ... My plotting software (Megastar v5.0.12) does not plot Berkeley 81. I only 'discovered' it by downloading a DSS image of NGC 6735, which is a very non-descript NGC open cluster around the 'bright' star to the right. In the Arizona Database v9, NGC 6735 is listed as "cluster of 35 stars surrounding SAO 142915" |
