This image was captured using my 10" f/4.8 reflector, a Vixen Atlux mount, PHD auto-guiding, an Atik 383L mono CCD camera and a set of Astronomic narrowband filters, H-alpha, SII and OIII.
I captured five minute sub frames with matching dark frames and combined them with flat fields to reduce the effect of vignetting in the final image.
The total exposure times were 60 minutes for each narrowband filter H-alpha, OIII and SII and 15 minutes using a blue filter.
