Read here: http://www.lightvortexastronomy.com/tutorial-sharpening-fine-details.htmlThis tutorial covers the process of sharpening fine details in one's images, be they monochrome or colour. The tutorial covers the in-depth use of
Deconvolution with
DynamicPSF on linear images (linearity is required for this) and
MultiscaleLinearTransform on linear and non-linear images.
ATrousWaveletTransform is normally used but as it is being phased out to obsolete by
PixInsight developers,
MultiscaleLinearTransform replaces it completely.
[UPDATE]: This tutorial is now back online after a corrective update.
Deconvolution with
DynamicPSF is now described strictly with linear images (as it should be). The order of presentation of
Deconvolution and
MultiscaleLinearTransform has been reversed to nail in the idea that both can be used -
Deconvolution while the image is linear and
MultiscaleLinearTransform later, ideally when the image is non-linear. Also made some edits to the text to ensure correctness and fluidity.
