This patch of nebulosity lies in the constellation of Cepheus the King commonly named the Wizard nebula.
The data were taken on two separate evenings with hazy sky conditions, on the first stars were visible down to magnitude 4.7 and on the second magnitude 4.
I was using my ten inch reflector f/4.8, a Vixen Atlux mount, PHD auto guiding, an Atik 383L mono CCD camera, a set of Astronomik narrowband and RGB filters. I captured five minute subframes 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 two hours and forty minutes using a H-Alpha filter, thirty minutes using an O111 filter, twenty five minutes using an S11 filter, and twenty minutes for each RGB filter, total exposure time of 285 minutes, four and three quarter hours.
