My work flow prior to PI was to calibrate all data using appropriate flats, darks, and bias frames, and then run the Kernel Filter to remove Hot/Dead Pixels. In MaxIm you can set a threshold of % for each and I've always used 80% for dead and 20% for hot pixels. I've just started looking at the Cosmetic Correction Module and not sure how to accomplish the same results. On the image I've been working on, a wide field image of the Cone Nebula, I've seen issues that are not present if I calibrate using MaxIm and run the Kernel Filters for Hot/Dead pixels, and then continue in PI. So that seems to be a factor. I don't think it's the calibration as I've always seemed to get a cleaner calibration when in PI with PI made master calibration darks and calibrated flats. Maybe I'm wrong but in the interest of moving ahead and learning something here I'd like some input. I do used dithered guiding BTW. Maybe it's in my rejection method when combining using Image Integration? Sorry to reference other software's but that's what I've used and know.
Thanks for any insight. I'll post cropped examples soon.
