I have just "discovered" the Filters ->Remove gradient -> Points function, which works better than the "automatic" methods in many cases. (perhaps AstroArt selects points within nebulosity/galaxies in auto mdoe?)
But when having multiple images from different filters, all images perfectly aligned, it would be very usefull, if it was possible to reuse the points that I have carefullt pointed out in the first channel, in the remaining.
So, is it possible to save the points and reuse?
