Having suffered a calamity with my polar alignment during a night time accident I spent quite a while correcting it. This is my first attempt at M13 in Hercules following the re-alignment. At 2am in the morning of 28th April 2013 I decided to grab 40 minutes worth of images to compensate for the hard work. 10 minutes each of LRGB using an Opticstar 145m-ice camera, Baader filters, Televue 102 and a Lodestar guide camera. processed in MaximDL and Photoshop CS3. Probably due to lack of sleep I could not correct the colours properly, so I converted it to black and white.
