Digital development processing applied for the initial stretch.
Iterative background smoothing applied to reduce background noise. Masked noise reduction
applied and then a highpass filter applied using Paint Shop
Pro. Star shrink
processing was applied and the layered shift darken combine
algorithm was used to reduce some minor star trailing. The image was
resized for web display and Focas Magic used for final sharpening.
