Newton type reflecting telescope i.e. handiscope, for use by e.g. reduced mobility person, to observe celestial object in sky, has optical tube containing parabolic mirror with desired focal length and diameter

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.
