[...]Maybe it would have been better to ask how many things can a telescope focus on at a time, one.[...]
Objects orbiting Earth, in our Solar System, in our Galaxy and beyond don't need different foci. They are all, in effect, at infinity when it comes to optics. We have taken single images that contain over a million stars in that one single shot. Several telescopes have wide-field capabilities as well and have multi-object spectrometers that measure spectra from hundreds of objects in one observation.
Please. The nonsense you wrote about telescopes is classic PT codswallop. Now you get yourself deeper into your fantasy land by demonstrating you know nothing about optics, telescopes or god know what you want to post about next.
"I also notice you are really not an optics guy. It has been about 3 or 4 times now that you don't have the perception to see when digital photos have been photoshopped."
I know the difference between coma and stars being trailed. You don't.
