I took this image under bright moonlight with stars only visible down to magnitude 4.
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. and a set of Astronomik narrowband filters.
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 60 minutes using a H-alpha filter, 40 minutes using an OIII filter, 30 minutes using a SII filter and 15 minutes using a blue filter.
