AGP2_Bicolor

This one is not much much to look at, being extremely small (angular size 34x 18)and faint (surface brightness 23.8 mag-arc/sec2). It was discovered in 1997 by inspection of the red POSS2 plates by Ali, Gajdosek and Pfleiderer:

It is estimated to be 28 Ly distant. There is no central star identified on the POSS plate, nor in my image ( not surprising with narrowband only ). Emission line analysis suggests that it is strong in NII>Ha>OIII. It is about 20 away from AGP2, a smaller PN discovered at the same time, but I could not squeeze them in the same frame effectively. Thanks for looking.
