IC1318, The butterfly nebula.

I took this image under very clear sky conditions with stars visible down to magnitude five. The telescope I was using was my ten inch f/4.8 reflector with a Vixen Atlux mount and an Atik 383L mono CCD camera. I captured five minute sub frames with matching dark frames and combinded 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 Olll filter and 40 minutes using a Sll filter.
