The Helix Nebula in Aquarius

Date   10/25/2005
Scope   Celestron C-11
Mount   Celestron CGE
Optics   6.3 Focal Reducer
Camera   Modified Canon 350D
Exposure   5 minutes at ISO800
Processing   10 images processed in ImagesPlus 2.75 beta 4, dark/flat/bias calibration, background comp, adaptive add, DDP, levels, curves, saturation
Notes   The Helix Nebula is one of the closest of all planetary nebulae and with an apparent diameter of nearly half of the full moon is also one of the largest in apparent size. In fact, I feel that this is really the largest deep sky object that I can confortably image with the C11 and 6.3 focal reducer.
