A section of the Veil Nebula, NGC6992, a supernova remnant in Cygnus.
This is the eastern section, known as "The Waterfall".
This image uses a stack of 18 ninety second exposures shot through a Hydrogen-alpha filter as the luminance channel,
and stacks of 3 sixteen minute exposures for each color channel.
The Luminance channel can be seen in the image below.
The color exposures were acquired using an SXV-H9 CCD camera on a Tele Vue NP-101 4" refractor
equipped with a 0.8x focal reducer, yielding an effective focal length of 430mm.
The exposures were calibrated, defect-corrected and stacked using AIP4WIN.
The color channels were combined and automatically G2V-balanced using AIP4Win's color tools.
This image has been resampled down from its original size of 1217x909.
