摘要

A correct image reflecting telescope with zoom capability comprised of a flat mirror, a parabolic primary mirror, and an image correcting system. The flat mirror reflects the incoming light from the telescope aperture into the parabolic primary mirror. The reflected light from the primary mirror passes back through a small centrally located opening in the flat aperture mirror and into an image correcting lens system. The image correcting system repositions the focal point of the primary mirror from a point in front of the flat aperture mirror to a point behind this mirror for observation with and eyepiece. The image correcting system makes the telescope useful in terrestrial as well as celestial applications and it can be moved with respect to the primary mirror such that a zoom feature results. This intrinsic zoom of the telescope allows an observer to use a single eyepiece in place of many, eliminates the need for an additional finder scope, and also makes the telescope useful in spotting scope applications. The eyepiece can remain at a stationary level for all observable directions.
