NGC 6992 - Part of the Veil Nebula


Found at the east side of  the Veil Nebula, NGC 6992 is part of a large super nova remnant..  It is found in the constellation Cygnus (The Swan).  It exploded somewhere between 5,000 and 10,000 years ago, and is 1,500 light years away.

The above image was intended to be an LRGB image, but when the luminance data was used, the color balance really didn't work.  Something to do with the emission lines that actually make up the "color" image?  The RGB data worked fine: two five minute Red frames, two 5 minute Green frames, and four 5 minute blue frames.  All frames were binned 2x2.  Taken at f/6.3 with the 12" LX200 and the ST-8E.  Color calibration by the numbers at 74 altitude (1.15 : 1.00 : 2.05).  Taken on July 31, 2000 at the Mistletoe site out side of Monmouth Oregon.

Previous attempt was monochrome:

This image is just a small part of the Veil.  It is the combination of 2 two minute exposures taken with the 12" LX200 and 416XT CCD at f/3.3.  It was taken in my back yard in Monmouth Oregon.

Taken Sept 3, 1999.
