A cool blue planetary nebula NGC 7008 appears to be resting peacefully in this night sky photo.
Astrophotographers Bob and Janice Fera took this photo August 8-11, 15-16, 2012 from Eagle Ridge Observatory, Foresthill, Ca. The duo used an Officina Stellare RC-360AST 14" f/8 Ritchey Chretien Cassegrain with a two-element field flattener and Apogee Alta U16M CCD Camera with Astrodon Filters. Multiple exposures are made to collect enough light for an image that would otherwise not be evident to the eye.
NGC 7008, also known as the Fetus Nebula, is a planetary nebula in the constellation Cygnus. The nebula is about 2,800 light-years from Earth. A light-year is the distance light travels in one year, or about 6 trillion miles (10 trillion kilometers). Cygnus is one of the most recognizable constellations located on the periphery of the Milky Way.
