Comment on What an unprocessed photo looks like

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?

It sure is! The monochrome sensors are also great for narrowband imaging, where the filters let through one specific wavelength of light (like hydrogen alpha) which lets you do false color imaging.
IR is basically the same. Here’s the page on JWST’s filters. No clue about xray scopes, but IIRC they don’t use any kind of traditional CMOS or CCD sensor.
