For a while the best/fanciest digital cameras had three CCDs, one for each RGB color channel. I'm not sure if that's still the case or if the color filter process is now good enough to replace it.

    There are some sensors that have each color stacked vertically instead of using a Bayer filter. Don’t think they’re popular because the low light performance is worse.

    At least for astronomy, you just have one sensor (they’re all CMOS nowadays) and rotate out the RGB filters in front of it.

    Is that the case for big ground and space telescopes too? I can imagine this could cause wobbling.

    Btw is that also how infrared and x-ray telescopes work as well?
