WebMar 5, 2024 · The guider/main pixel ratio is ~1.5. So for every 1 pixel dither on your main camera, you will need to dither 1.5 pixels on your guider. If you want to dither 20 pixels on the main then you will need to dither 30 pixels on your guider. How many pixels to dither depends on your fixed pattern noise scales. I cannot give you an answer for that.
