Description:
Easily visible ring at 131x. The diameter of the planetary is approx 50 and it 
is perfectly round. The center is darker but still slightly illuminated by a 
faint glow. Increasing the magnification to 342x darkens the nebula a bit but 
more details are visible now. The N-part of the ring is brighter than the S 
part. The ring also appears fragmented into brighter and dimmer segments. ENE 
of the center and close to the edge a 13mag star is visible. No signs of a 
central star, though. Nice interesting planetary that is in gross contrast to 
the nearby Bug Nebula.
