This image was taken with my 10 inch f/4.8 reflector, a Vixen Atlux mount, PHD auto-guiding and an Atik 383L mono CCD camera.
I captured five minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of vignetting in the final image.
The total exposure times were 40 minutes using a H-alpha filter, 30 minutes using an OIII filter, 15 minutes using a blue filter and 80 minutes using an IDAS filter for luminance.
