This patch of nebulosity lies in the constellation of Vulpecula the Fox.
This image was taken on two separate evenings with hazy sky conditions , stars were only visible down to about magnitude 4.5.
I captured five 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.
I was using a ten inch f/4.8 reflector, a Vixen Atlux mount, PHD auto guiding, an Atik 383L mono CCD camera, a set of Astronomik RGB and narrowband filters H Apha, O111, S11.
The total exposure time was 150 minutes using a H-alpha filter combined with some old H-alpha data making an exposure time of 250 minutes, the O111 exposure time was 60 minutes, 40 minutes for S11 and 20 minutes for each RGB filter.
