Pixel Arithmetic: Square pixels.
This is a necessity as this camera's pixel size is 8.6 x 8.3. You get all kinds of annoying horizontal lines in your debayered images if you don't do the pixel arithmetic first.

Image stacking also in FitsWork4 with 12 alignment points drawn manually. On the fly repair of hot pixels per frame. (Didn't really know about dark frames back then).

Image processing in Startools.
Final smart sharpen in Photoshop.
