This patch of nebulosity lies about one degree east of the bright star Deneb in the constellation of Cygnus the Swan. I piggybacked a 135mm lens using narrowband filters attached to the front of the lens. I was also using a Vixen Atlux mount, a ten inch reflector and an Atik 383L mono CCD camera.
I captured two minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image.
The total exposure time was 40 minutes using a H Alpha filter, 30 minutes using an O111 filter, 25 minute using a S11 filter and 5 minute using a blue filter.
