The Zeta Orionis Nebula

Emission/Dark Nebula in Orion

Uploaded 3/16/2001

A low surface brightness object near the star Zeta Orionis (upper left), often difficult to photograph in bright skies. This deep exposure is an LRGB composite, of numerous exposures. This image was guided with the SBIG ST-4 Auto Guider, and clearly shows the gradation of colors from orange to red in the interior regions. This color difference is due to obscuring dust.
