A compound telescope (telescope Catadioptic) is a reflex optical telescope that uses reflection to saengklap so that the camera the size of a shorter torso. Using the mirror, convex secondary mirror provides a condensed beam allows short beam camera compact, but still expanding the image height 5 glass works, how the embossed image which occurred on the plane of focus is the curve. Therefore, it is necessary to install the lens, adjust the resolution (Correction plate), Pak lam cameras to work with the secondary mirror. In order to compensate for the curve of the plane of focus. By modifying the lenses do not influence the optical integration and expanding capacity at all.
