looking on the ray diagram ,we can conclude that the image formed due to this telescope is oriented same as to what is actually in space.

The Cassegrain telescope is an astronomical reflecting telescope, in which the light is incident on a large concave paraboloid mirror, and reflected onto a smaller convex hyperboloid mirror. This reflected light is reflected again through a hole in the concave mirror to finally form the image.

The classic Cassegrain telescope consists of a parabolic reflector (primary mirror) and a hyperbolic mirror (secondary mirror). The parabolic shape of the mirror helps in gathering light, similar to the way that a refractor gathers light using an objective lens. The hyperbolic secondary mirror reflects light, such that it is focussed onto the hole in the primary mirror. The eyepiece and the other instruments are located behind the telescope. The folded optical path in this telescope makes it compact and portable.

Question: An astronomer is working with an optical telescope. The telescope lenses focus images onto a high-resolution, CCD imaging array, and the images are then converted by the telescope electronics into digital images. Working late one evening, the astronomer notices that her new images are noisy and blurry. The manufacturer tells the astronomer that the unit is operating with specifications. Trying to improve the situation by constructing controlled lab experiments with the lenses and imaging sensors is not possible because...
