摘要

The telescope has an optical tube (1) containing a parabolic mirror (2) with desired focal length and diameter, where the optical tube includes Barlow lenses (6), focal reducer (7) and an exchangeable eyepiece (8). The parabolic mirror projects a focal point on a plane mirror (3) at 45 degrees. A focal point obtained from the parabolic mirror passes via a motorized focuser (4) that is operated using a box, where the box includes multiple pushbuttons (5) and is accessible by a handicapped person using a hand.
