IC1848, the Soul nebula

Here we have another section of the Soul nebula in Cassiopia.
The clouds were moving in fast on this particular evening and I only had 30 minutes of imaging time using an Astronomik H-alpha filter. The colour data however were taken from an old wide angle narrowband image using an 80mm refractor. The luminance data were taken using my ten inch f/4.8 reflector an Atik 383L mono CCD camera with PHD auto guiding. I captured six, five minute subframes with matching dark frames and combined them with flat field frames to reduce the effect of vignetting in the final image.
