Description

Located roughly 2,400 lightyears away, the Cygnus Loop is a magnificent filamentary nebula. This nebula covers 3 degrees across the sky, or roughly 6x the diamter of the full moon. While the Cygnus loop glows brightly in several distinct wavelengths of light, in this rendition we are primarliy observing in ionised Hydrogen Alpha and the forbidden line of Oxygen III. 

Inside the Cygnus loop there are several well know sub structures, such as the Eastern Veil Nebula, Western Veil nebula, The Witches Broom and Pickerings Triangle. In dark skies, and with an appropriate filter and telescope aperture, this deep sky object can be observed visually.
