Here's a first quick processing of last night's attempt. The night began extremely hazy and moist, cleared and dried up a bit after midnight but come dawn the humidity rose to 90%+ according to the observatory meter!

This object was the first planetary nebula to be discovered; by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and its diameter of about 8 arcminutes, it is easily visible in binoculars, and a popular observing target in amateur telescopes. source: Wikipedia
