Bigger telescopes are mostly about capturing more photons to detect fainter objects. They don't really give you better resolution in most cases. Technically, a bigger telescope can give better resolution, but from the ground, the limit is usually atmospheric seeing. From orbit, it will be down to the quality of the optics, the resolution of the detector, and the precision of the tracking.
- dylan604 3y agoThis is very much a basic misunderstanding with telescopes. Most people expect magnification. The amount of photons absorbed is something of a very esoteric concept to the uninitiated.
