The image was taken from Georgetown with my TMB-130SS refractor with a QSI-540 camera and Astronomik narrow-band filters. Individual exposures were 30min. Total times were 9hr in SII (Red), 5hr Ha (Green), and 14hr OIII (Blue).

North American Nebula in Narrowband
After two weeks of collecting narrow-band data, I put together an image of the North American Nebula in Cygnus (NGC-7000). The image is focused around the "gulf of mexico" region of the nebula, though to me it looks more like the head of a galloping horse at that field of view.
