This happy little fellow is a planetary nebula discovered by William Herschel in 1785. The Skull Nebula is located in the constellation Cetus. From our vantage point, it has an angular resolution of just 3.7 arcmin. The estimated diameter is about 2.3 light years, and is 1,600 light years from our planet. It has a fairly low surface brightness at around 11th magnitude. Quite often, visual observers can find the foreground stars overpowering when trying to locate this planetary nebula. The central star is fairly bright at 11.8 magnitude. The eastern limb of the nebula is brighter suggesting that it is interacting with the interstellar medium. This is an excellent example of how some objects exhibit bow waves truly reflecting the dynamics of the interstellar medium.

I tried to capture the ethereal shell of this planetary nebula. It reminds me of a crystal sphere just hanging in space. The teal and red colours of the planetary really seem to add an element of extra depth to the image.

Thanks for looking.
