Tonight turned out to be a pretty good imaging night, pretty good seeing.
here is another "bright" planetary nebula that escaped the NGC catalog. Its very close to Rigel Kentaurus. Unfortunately scattered light from it appears on the image as a slash across the bottom and also a semicircular band with a hole in it.
In the full res. crop there are red diffuse spots near top right. Doesnt appear on Star Atlas Pro even though SAP goes very deep.
Theres also a tiny thin line of nebulosity extending from lower left of He2-111.
Also note the small open cluster that seems unusually yellow compared to the rest of the stars.
Image is 7x10 mins ISO400. LPS filter. MPCC coma corrector. modded 350D. 10 inch f5.6 newtonian, off axis hand guided as usual.
