NGC 246 - The Skull Nebula - 171208 CR

NGC 246, the Skull Nebula, is a relatively large planetary nebula in the constellation Cetus. It is roughly 1,600 light-years away from Earth. The nebula's central star is a 12th magnitude white dwarf, HIP 3678, and is one of the hottest known stars in the galaxy (200,000 C).

According to Wikipedia, some amateur astronomers refer NGC 246 is known as the "Pac-Man Nebula", but I think that's a mistake and was really a reference to NGC 281.

This image is a stack of sixteen ten-minute exposures, taken with my QHY247C at default deep sky gain settings on the 11" Edge HD. The subs were stacked in DSS, and processed in a combination of PixInsight and Photoshop. This image was cropped and rotated from the full sized image to illustrate the "skull" appearance. You can see the full framed image here.
