I have been recently beta-testing Noel Carboni’s new flattening tool for deep-sky images.

This plug-in makes flattening even the most difficult image data a doddle (even I can get good results).

If you carry out deep-sky image processing, then you must have this tool in your digital darkroom toolbox – it’s sharp!
