Hi there! Thanks for the link. Works as described. Only problem: Photoscan can only "undistort" images, but not re-distort them. So it can't create the needed STmap out of the box. Maybe it could be faked by inverting the lens distortion parameters manually, have to check that. Would be alot of manual work and I'm not sure how to deal with the necessary overscan. But if it's the only way, I'll give it a try.
