NGC 6781 Planetary nebula in Aquila
« on: August 24, 2016, 04:49:23 pm »
17.5" (7/12/99): at 100x appears fairly bright, round, ~1.6' diameter with a
darker center.  I used a variety of magnifications and filters but the most
interesting view was at 220x using a UHC filter.  With this combination the PN
is slightly elongated E-W and clearly brighter along the southern rim with the
brightening tapering towards the ends so this brighter portion had a crescent
appearance.  Because of this asymmetric rim the darker center seems offset and
only weakly brightens at the NW rim.  A mag 13 star is just off the NE edge 1'
from center. (NGC/IC Project)

A very nice surprise in the night  :)
