For the first time I could use my IR/UV block and IR pass filters. I made 2400sec exposures with the IR/UV block filter (RGB frames) and the IR pass filter (luminance frames). From each avi I stacked 800 of the best frames, totalling into a 80sec RGB and 80sec IR picture. I combined both pictures with photoshop into the following picture. The result is a lot better than my previous attempts without the filters. By using a 2x barlow the effective focal length in these exposures was 2000mm.
