For those of you who have been tracking the evolution of this image, and in fact any of the images taken with my Atik 11000, you will have noticed the horrid dead column of pixels on all the images.
In this iteration of the Rosette, I removed it by hand (mouse) in Photoshop.
Pretty happy with the results. Also tried a less aggressive stretch.
Thanks to everyone for your advice and suggestions.
