This is a ten shot panorama of the North America Nebula and surrounding Cygnus region. It was processed with minimal stars, just the most prominent ones, and is a combination of RGB and H-Alpha images. The Ha shots were taken using a screw on filter which, while not being very narrowband filters at 20nm, are much easier to use than the typical clip in variety. This one was shot in Northam, 1.5 hours east of Perth in Western Australia.
