Description It was pretty hard finding information about this rarely imaged planetary nebula in the Abell catalog and this may be one of the few colour images taken of it. The magnitude is 17.5 with a 20.9 magnitude central star and it is about 1.2 arc-minutes across.  It is apparently visible in a 16" telescope under good conditions.
