Kn63 was discovered around 2010 by Matthias Kronberger of the Deep Sky Hunters group. It's acquired the nickname “Medallion Nebula,” apparently because of its location near the neck of Orion. The progenitor star appears to be the very faint blue star at center. It’s about 6 arc minutes in diameter, and is so faint that it barely registers even in long exposure CCD images. OIII is much stronger than Ha (which isn’t saying much!). I found only two images of this PN other than the verification image taken with the Kitt Peak 2.1m reflector - a very nice one by Peter Goodhew on Abin and a very deep one from CHART32 with the 32-inch reflector in Chile.
This image uses OIII for luminance for the PN and maps Ha:OIII:OIII to R:G:B for color. The stars are separate RGB data. Full details on capture and processing are at the link.
