Hi all,
I just published a new tutorial: Multiscale gradient correction. This article gives an in-depth description of a novel method for correction of light gradients in astronomical images. This new method uses observational data to deliver much more reliable and accurate results than any software-based solution, especially in images of low surface brightness objects contaminated with strong and complex gradients, as well as deep images without free sky background areas.
The article includes a detailed description of the new gradient correction technique, a step-by-step implementation in PixInsight, several practical examples, and important conclusions. I hope this material will be of the maximum interest for you all, especially because the new method has the potential to introduce a radical change in the way we face these important image processing problems.
Best regards,
Vicent.
