I wanted to really go deep on this rarely imaged planetary nebula to see how much detail I could pull out.

NGC 7008 (PK 93+5.2), also known as the Fetus Nebula is a planetary nebula with a diameter of approximately 1 light-year located at a distance of 2800 light years in northern Cygnus. It was discovered by William Herschel in 1787, in Slough, England. NGC 7008 (H I-192) is included in the Astronomical League's Herschel 400 observing program.
