Still having issue with calibration of images using flats and dark-flats. I don't know if it's a problem with the images coming from the camera or what. Even my darks do not seem to want to calibrate out any of the hot pixels. Both flats and darks seem to introduce a terrible gradient that is difficult to work with. I've not had an issue until the last couple of images.
