NGC6960

NGC6960 The Veil Nebula. This Image was taken under clear mooless sky conditions with only light pollution to contend with. A f/7, 80mm refractor was used, with PHD auto guiding and an Atik 383L monochrome CCD camera. Ten minute sub frames were captured with matching dark frames and then stacked them using Deep Sky Stacker. The exposure times were 120 minutes using a H-alpha filter, 80 minutes using an Olll filter. These narrowband exposures were used for the image luminance were as the RGB filters were used for the colour data. The exposure times were 20 minutes for each colour filter making a total exposure time of four hours and twenty minutes.
