NGC 7814

NGC 7814 . This galaxy lies in the constellation of Pegasus . I was using my ten 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 was 90 minutes using an IDAS filter, 15 minutes using an O111 filter, 25 minutes using a H-alpha filter and ten minutes using a blue filter.
