Data collected with a 10 inch RCOS Ritchey Chretien on an AP1200GTO Mount, SBIG ST-10XME/CFW10/AO8 with water assisted cooling. 24x300s (Shorter exposures because the local light pollution was very bad) LRGB all binned 1x. Sub Exposures calibrated, aligned and stacked in CCDStack. Final color combine using Photoshop CS2. First exposures made using AO8 Adaptive Optics unit. Guiding was @ 1.2Hz. A lot of gradient removal techniques was done to minimize the effects of the local Light Pollution.
Effective Focal Length 2290.4 mm ~ .61" per Pixel
