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.

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).
