M29

M29. This open star cluster lies deep with in the constellation of Cygnus the Swan. I took this image under very clear sky conditions and bright full moon light. I was using a ten inch f/4.8 reflector, 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 30 minutes for each RGB filter and 60 minutes using a H Alpha filter.
