Not sure if this is a Physics related or Engineering related question, but imagine that we would take 100's of small hobby telescopes and somehow managed to point them all at the same point in the sky at the same time. We would than digitally process this image.
Would we be able to combine these images and get image quality of a much larger telescope? We assume that all of them would point at a same part of sky at the very same time. Do you think we could get a significantly improved image compared to individual telescopes? And if so how much of a better image would we get?
