Yes, the resolution is given by the diffraction limit of the optics that is dependent by the diameter.
But resolution is different from brightness.
If you tried to take a video of the same scene with a telescope chances are that the final result would have been darker, even using the same camera.
Granted that it would have had a much much better resolution (but a much much smaller FOV)
- greglindahl 10y agoSo you think astronomers are too stupid to trade resolution for brightness? Hint: downsample your image: you won't lose too much as long as the dark current isn't too large.
- tigershark 10y agoThey have completely different use cases. In one case you are making a video of a scene with a FOV of several tens of degrees. In the other you are observing objects with a maximum size of a couple of primes and with features measuring infinitely small fractions of arc seconds.
