On Friday night we had reasonably good weather conditions and no moon so we made for our dark sight and went hunting for the Eskimo Nebula (NGC 2392). The nebula is known as a double-shell planetary nebula and resides in the constellation Gemini. It got its name for the outer shell of gas that looks a bit like a the furry trim of an Eskimo's parka. The other important fact about this object is that it's a planetary nebula which makes it a good target for am OIII filter as it gives of a particular wavelength of light. I was able to use my OIII and a 2x Barlow lens to get in relatively tight and bring up some nice resolution for this relatively small object. It will be fun next time to try without the OIII filter to see some true color.
