Personal "rating" (at this aperture, and sky condition):  B-
Very small, round.. only a slight green-blue hue, hardly noticeable, making 
this object seem like a slightly out of focus star until you get to high
power. Of little interest until one notices the approximately 14+ 
magnitude star roughly 5 arc seconds away making this appear as a 
tight double star with one object a planetary nebula!
