All shots were guided using the AO7 using just the mirror tilt/tip. I couldn't be bothered calibrating the mount axes. Luminance was 4x300 sec subs, RGB 5x120sec subs (binned 2x2). Captured using CCDSoft. Calibrated, registered and median combined using CCDStack. Colour synthesis and Luminance layering in PS CS2.
Scope is permanently mounted and drift aligned in a ROR observatory. See Mark at Myhouse Kennels and Cubbies for one!!
