IC443. This nebula lies in the star constellation of Gemini the Twins. I took this image using my ten inch f/4.8 reflector, an Atik 383L mono CCD camera and with 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 colour data I used is the Hubble palette, using Sll for red, H-alpha for green and Olll for the blue. The total exposure times was 40 minutes using a Sll filter, 40 minutes using a H Alpha filter and 20 minutes using an Olll filter.
