G255.8+10.9 (FP0905-3033) is an extremely faint 11′ planetary nebula in the southern constellation of Pyxis. It is described as an “interesting one-sided planetary nebula confirmed spectroscopically and with CSPN” (central star of planetary nebula). There is little technical information about this object and few images, so this image may be the deepest available, showing both the arc-shaped OIII and H-a + N[II] emissions. It is embedded in emission nebulosity, likely part of the large Sharpless Sh2-312 emission nebula. The planetary nebula structure was brought out with narrowband filters and short RGB data were added for star colors.
