Possible camera problem ... I had dropped it from about 1m onto brick paving on 16/10/2012 - no superficial damage, but shutter and mirror lock-up issues during this sequence. DeepSkyStacker 3.3.2 Stacked 85% of 15 Images ISO 800 120 Sec, 96 DARK, 53 BIAS, 0 FLATS, Post-processed with Adobe Photoshop CS5 Telescope - Bintel BT200 f/4.0 Newtonian (borrowed from Stephen Boyd) with Baader MPCC Coma Corrector, Hutech LPS-P2 filter, Canon 40D DSLR field 64' x 95', Ambient 16-15C. Mount - Skywatcher NEQ6 Pro. Guidescope - Orion ShortTube 80 with Star Shoot Auto Guider.
My first attempt at this from the darker sky at Perth Observatory (30Km East of Perth CBD), however with a 25-day old moon rising during that last half of image capture. It needs more light and with the unmodified DSLR am struggling to pick up the tenuous red Hydrogen-Alpha regions. See also cropped version.
