NGC 7662: The Blue Snowball

This intricate nebula is a popular target for amateur astronomers with small aperture telescopes. Distance estimates vary widely, from 1800 lightyears to 5600 lightyears. The Hubble Space Telescope captured a lovely image of this nebula, and it was featured as an APOD back in 1996.
