I have been playing with the colour calibration tool and it seems to work very well , I would be interested in when people run
this Ie Before a sat stretch or after a sat stretch  or very last thing

I have been having problems with it on the first image I tried.
It is my shot of the NGC in the leo triplet M65- 66.
Color bkg neutraliztion went fine.

I can't the get wavelet and noise settings to select the stars only for the white balance.
I would think this would be easy.
The generated mask does not show white where the star are. Tips helpful. I must be missing something basic.

Hi Max

I left the wavlet and noise setting alone and raised the lower limit to 0.1 which seemed to work for me!
Perhapes I was lucky for a change

Hi Max,

Again, to say something useful I need to take a look at the image in question. As a general advice, the PreviewAggregator script (by David Serrano) may save your day. Have a look at this:

This figure is from the prerelease information post for version 1.5, where you'll find more examples and comments:

PreviewAggregator allows you to gather a set of previews, conveniently defined to select areas without nebulosity etc., into a single image. Then you can use the aggregated image as the background and/or white reference (in the example above, aggregated previews have been used for both tasks because the image has little free sky areas). This simplifies and greatly improves star detection. Give it a try.

Harry that did the trick.
