Sixty minute exposure (30*2 minute subs) at ISO 1600.
Stacked using Deep Sky Stacker. SIM processed in Paint Shop Pro.
Seeing was poor resulting in a soft image and light polution produced a gradient across the picture.
The gradient was removed with a masked brightness and contrast adjustment layer. A custom deconvolution routine was run in MathCAD on each of the red, green and blue channels. The channels were recombined and a final sharpening was done in Paint Shop Pro.
