The large, bright planetary, M27 looks wonderful in this size scope, 
even with a full moon some 10-15 degrees off the horizon! The 
UHC filter added an incredible amount of contrast.
Object looks like a large rectangle at first glance, with a noticeable
"tucking in" 
in the middle of each long side of the rectangle, producing a superimposed 
"hourglass" shape...nebulosity nevertheless still appearing approximately 
rectangular when looking at this as a whole. Sprinkled nearby is a myriad of
dim stars.
Best at around 50x, at this aperture.
