The North America Nebula, NGC7000 in Cygnus. This image is a stack of 10 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. The exposures were stacked using AIP4WIN. This image has been resampled down from its original size of 1040x1392.
