THE VEIL NEBULA - EASTERN PORTION (NGC 6992)

The Veil is a beautiful remnant of an ancient supernova.  It is far too large to capture in a single field with most telescope systems.  The entire Veil Nebula is sometimes called "The Cygnus Loop".

These images show the Eastern region of the Veil.

The image below was taken with a Takahashi Epsilon 180ED at f/2.8, on an AP1200 mount, with an ST-10XME and AstroDon 6nm narrowband filters.  The image is in "false color" - I first created an image mapped with the CFHT scheme (Ha=Red, OIII=Green, SII=Blue), then another mapped with the Hubble Pallet (SII=Red, Ha=Green, OIII=Blue).  I then mixed them together to emphasize variations in the emissions.  Taken in my backyard various nights in October, November, and December 2008.
