This image was taken under clear, moonless sky conditions with stars visible down to magnitude 5.3. I was using my 10 inch, f/4.8 reflector, a Vixen Atlux mount, PHD auto-guiding and an Atik 383 L mono CCD camera.
I captured 5 minute sub-frames with matching dark-frames and used flat-fields to reduce the effect of vignetting in the final image.
The total exposure times were 15 minutes using an OIII filter, 30 minutes using an H-alpha filter and 25 minutes using a SII filter, and 10 minutes using a blue filter.
