Brian, using photoshop CS2, I use the brush tool and select "saturation" in the mode box. Using the tool over stars takes out the blue but it also leaves a black hole. To fill in the hole I copy the original image, convert it to LAB colour. In the channels box I select "lightness" and copy to clipboard. Going back to the touched up image I paste the layer in from LAB colour selecting "luminance". Basically it's just a luminance overlay from the original.

Morton, yes from Andrews. Perhaps I will ring them next week. The rainbow flare is a worry.
