PM1-333 is a small (70 arc seconds) planetary nebula in the constellation Cepheus. It was discovered by Andrea Preite-Martinez in 1988. I believe this to be the deepest, and highest resolution colour image of this target. The tiny blue progenitor star can just be made out dead centre of the image.
It lies within IC1396 where it appears as a small dot at the bottom left hand corner in J-P Metsavainio's excellent image 1.bp.blogspot.com/-JEMi-QvpB0Q/XicHMRDQXbI/AAAAAAAARug/ECBNZGRTptwRSAOExQSKmmvCIZWz6niCACLcBGAsYHQ/s1600/IC1396Det.jpg
