Three iterations of masked
stretching and split star processing
used to enhance the image. At each iteration a starless mask was
produces and used for the initial stretch of the original image in the
next iteration. Masked noise reduction using a frequency
domain lowpass filter applied to the DSO layer and then it was
recombined with the star layer. A final edge masked high pass filter
was used to add some contrast to the dust cloud. Image binned 2 by 2.
