WebDifference between Maksutov-Cassegrains and Schmidt-Cassegrain. Their main difference is the corrector lens at the front of the telescope. Both of them use spherical mirrors that induce spherical aberrations. This is where the corrector lens comes in, getting rid of this disturbance so the observer can have the best image quality while ...
