Saturn in IR and Visible light

I think the seeing was a bit bad, or I had something wrong with my setup. I did check my collimation and it seemed to be fine. But still focusing was pain. Can't blame the focuser, nor the image scale this time. Dew was also causing harm, it was +2°C outside and humidity was close to 100%. So assuming it was seeing, I tried to use IR pass to see if there is notable difference in detail. The IR image (grayscale) may have a bit distinctive gap on Cassini division. I had to push gain up, because image was too dim, so I got a lot of noise and had to stack more images. Still there is lots of noise left.
