Processing Raw images calibrated and stacked using Images Plus. 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.
