Notes:*

I tried to image some high surface brightness planetaries on a rare clear night during monsoon clouds. This, and NGC 6884, were imaged the same evening while rising in the east ...

*Also called "Campbell's Hydrogen Star" ... the listed size of 35 arc seconds seems to refer to the over-exposed POSS / professional images. My very short exposures / short total time presents a smaller object, but has no interior detail that I can bring out. See this information from DeepSkyForum.
