M31 - third attempt
Third attempt at M31 and my second reprocessing attempt. After watching Adam Block's excellent PS tutorial (Cosmic Canvas) I decided to incorporate two additional techniques into my PS workflow: Shadows and Highlights for increasing colour in the RGB image and HDR toning for increasing contrast in the synthetic luminance layer. LIGHTS: 42 x 300s + 23 x 600s; DARKS:30; BIAS: 100; FLATS:40. Taken with a Trius SX-26C and SW ED80.
