This patch of nebulosity lies deep within the constellation of Cygnus the swan.
I captured this image using my 80mm, f.6.3 refractor, a Vixen Atlux mount, PHD auto-guiding, an Atik 383L mono CCD camera with a set of Astronomik narrowband filters, Sll, Olll na H-alphs.
I captured five minute sug frames with matching dark frames and combined them with flat field frames to reduce the effect of vignetting in the final image.
The total exposure times were 60 minutes for each filter.
