| 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.
