Notes:* I had one night when it wasn't overcast and/or raining, and tried to image a high surface-brightness 'planetary' ... This was imaged in so-so seeing and occasional high clouds. I used 96 out of 127 subs on this image, as the clouds and seeing made quite a few unusable sub exposures.

This appears to be a proto-planetary nebula. See CDS image/data.
