Comparing optical instruments is very difficult. There are numerous variables involved, the performance is not a single number, and the theory is complex. Perfect scenario to baffle amateurs. Also, it sounds like you may have been listening to the wrong rumors. The architecture of a telescope (refractor, reflector, catadioptric) is one of the least ...

The differences are in the designs: Newtonian: Gallilean: Schmidt-Cassegrain: Schmidt-Cassegrain telescopes are characterized by including 1 convex mirror, 1 concave mirror and 1 correction plate.

Yes, it is possible to use the sun as a gravitational lens and to achieve better telescopic viewing. As you know space is curved by mass and so light is deflected by mass, it is possible to focus light using gravitational lenses and thus achieving greater telescopic viewing. However, the sun does have corona fluctuations around it. So, to better exploit the ...

You will typically find that CCD cameras are sold separately to the telescopes. That way the telescope can be used visually or for astrophotography, by either fitting an eyepiece, or a camera. Most telescopes do ship with eyepieces, as they are much less expensive than a CCD and it is sort of expected, but most observers will typically replace this eyepiece ...

There are many other variations on telescope designs others than the ones you have mentioned. They differ in the light path, the shape of the optics utilised, the use of mirrors and/or lenses, and the physical structure. A Schmidt-Cassegrain is a particular type of Cassegrain reflector. A Cassegrain reflector uses two mirrors, a primary and a secondary. ...
