A section of the Veil Nebula, NGC6960, a supernova remnant in Cygnus.
This is the western section, known as "the Witch's Broom".
This image is a stack of 9 eight minute 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 shot with a bright moon in the sky.
The exposures were calibrated, defect-corrected and stacked using AIP4WIN.
This image has been resampled down from its original size of 1040x1392.
