Description: 70x: Almost stellar. The color (bluish) separates
it easily from the white field stars. At 390x it is clearly non-
stellar with a nice well-defined disk. The edges of the disk
seemed to be slightly brighter. There is a brightening on the NW
edge which reaches almost to the mag 11.2 central star.
