These two patches of nebulosity lie in the constellation of Cassiopeia the Queen.
This image was taken using a 135mm lens, Astronomik filters attached to the front of the lens piggybacked on a ten inch reflector mounted on a Vixen Atlux mount with an Atik 383L mono CCD camera.
I captured three 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 90 minutes using a H Alpha filter. 60 minutes using an O111 filter, 30 minutes using an S11 filter, and 12 minutes using each RGB filter.
