I have found this publication which may give some insight into the sharpening techniques used for hubble images. I suspect some of the developers can understand the complex formulas and weave their magic.
https://www.researchgate.net/publication/252709898_APEX_blind_deconvolution_of_color_Hubble_space_telescope_imagery_and_other_astronomical_data BTW, I have just looked at the new diffuse or sharpen module. It is not for the faint hearted, but I will explore it in more detail as it showed good promise on a very challenging image I tested it on. The preset was way too heavy for the image but reading the user guide I started getting some better results. Is the diffuse and sharpen module based on wavelets? I am trying to get my head around the meaning of the four orders.
