I thought modern telescopes use software to merge images across a period of time / from multiple telescopes to get a significantly higher resolution than that achieved through the physical limitation of light. At least that’s how all the spy telescopes work and how various ground based telescopes collaborate afaik. That’s in addition to gravitational lensing effects.
