Description:
A large, very faint, circular nebulous patch of uniform brightness. There
is no detectable brightening toward the core. Several foreground field
stars overlay the galaxy. Located with averted vision at 77x by sweeping
the field for an area slightly brighter than the background. Once located,
it was suprisingly easy to see but would promptly disappear into the
background each time an attempt was made to increase magnification.
