IC 5150, a Planetary Nebula in constellation Grus.
This rarely imaged southern planetary is dimmish, magnitude about 12. Due the full Moon, it's imaged with narrow band filters. Only H-a and O-III are used to compose the natural bi-color version.
This object will be better imaged with a broad band LRGB, since it emits some strongish continuous spectrum but as mentioned, the full Moon prevent me to do so.
I haven't seen any narrow band color images of this earlier!
