A section of the Veil Nebula, NGC6992, a supernova remnant in Cygnus. This is the eastern section, known as "The Waterfall". This image is a stack of 18 ninety second exposures shot through a Hydrogen-alpha filter. The exposures were acquired using an SXV-H9 CCD camera on a Tele Vue Genesis SDF 4" refractor equipped with a 0.8x focal reducer, yielding an effective focal length of 430mm. This image was acquired through a high haze layer. The exposures were stacked using AIP4WIN. This image has been resampled down from its original size of 1032x1374.
