Notes: I was searching for objects to image with a high surface brightness, and were away from the nearly full moon, and I thought I would try a couple of small planetary nebulae in Hercules.
However, this one is too small. It appears stellar at my focal length/exposure time.  See the other planetary nebula I imaged (PK 75+35.1).
The marine stratus (fog) has been very aggressive this week, and had covered me up before dark several nights on this imaging run.
