NGC6946 . Commonly named the Fireworks galaxy. This face on galaxy lies in the constellation of Cepheus the King . I was using a ten inch f/4.8 reflector a Vixen Atlux mount an Atik 383L mono CCD camera and PHD auto guiding . 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 60 minutes using an Idas filter , 35 minutes using a H-alpha filter , 25 minutes using an O111 filter and 15 minutes using a blue filter.
