Description:
Very small, circular, almost stellar planetary nebula. In the eyepiece at 177x it was clearly a planetary with a light blue green cast. The nearly full moon was rising but did not interfere with my view. It was more difficult to see with direct vision, but by using averted vision it was very easy to pop it into view. This object was surprising easy to see for it's size and small diameter. Jumping to 325x did not improve the image or reveal any additional structure.
