NGC 2371/2 is a fascinating little planetary nebula in northern Gemini placed midway between Castor and Pollux. When this nebula was discovered it was thought that it was actually two separate objects, hence the two New General Catalog (NGC) numbers. The core nebula shows two clearly resolved lobes with two faint outer arcs. The seeing was pretty rough when this image set was taken so I down-sampled it a bit to keep it from looking too soft. I’ll be taking another look at this nebula on an evening with better seeing.
