SH 2-112

Show astrometry data

Sharpless 2-112 is a rarely imaged diffuse emission nebula in the constellation Cygnus, approximately 5,500 light years from Earth. This image shows the nebula and surrounding region in the Hubble Palette, where data captured through Sulfur 2, Hydrogen Alpha and Oxygen 3 filters are mapped to an image's Red, Green and Blue channels respectively. The stars appear in their natural color thanks to a series of short RGB images (totalling 1-1/2 hours).

This image was taken with our remote telescope in Rowe, New Mexico, and processed in Bangkok.
