Description:
I used both 112x and 188x.  Definitely elliptical, major axis running
north/south.  One faint star (looked up in atlases, possibly around
mag. 12?) near the south tip.  Definite nebula inside the ring, just
much fainter.  Nebulosity continuing well outside the 'ring' when
viewed with a UHC filter.  With high enough powers it is really
spectacular, because the outside ring is so much more distinct than
the inside and outside areas.  Very nice.  Still can't even catch a
glimpse of the central star.  Need darker skies.
