WebNov 23, 2024 · I have a 130pds newtonian reflector with a coma corrector, and am happy with it. It has a short focal length (650mm) and so is wide field. It is a lot cheaper than an apochromatic. There is an extra challenge with balancing a newtonian, as I have to rotate the telescope within the mounting rings. (I find it hard to explain why. WebDifferences Between A Schmidt-Cassegrain And Reflector Telescope. There are a whole variety of differences between these two optical variations which include the following : SCT’s produce much larger focal lengths over similar sized reflectors making them far better for planetary viewing. SCT’s tend to be far smaller in frame over similar ...

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 ...
