NGC 7008 is a planetary nebula located in Cygnus. it is sometimes called the Fetus Nebula. The shell is unusual in that it appears to have two different shells. One possibility that it was a binary star system with two different shells formed from each of the stars as each star with through the same red giant phase.

M57 also called the Ring Nebula is a planetary nebula (planetary nebula have nothing to do with planets). They are formed when a star near the end of its evolutionary life expels its outer layers as it shrinks down to the white dwarf stage. The planetary nebula name comes from the early days when nebula such as this looked like planetary disks to the early observers.

NGC 2261 - Hubble's Variable Nebula. Patterns in the nebula vary over time probably due to dust clouds that cover the star R Monocerotis at the tip are casting shadows on the illuminated nebula. Located in the constellation of Monoceros. It is at a distance of 2,500 light years away. The star R Monocerotis is a T Tauri type of variable star which is an young star that hasn't yet entered the main sequence for stars. Imaged over several nights with an Explore Scientific 127 mm refractor and Atik 314l+ mono ccd camera using Clear, Red, Green, and Blue filters.
