## Abstract

A telescope with an anti-shake mechanism is provided, including an eyepiece, an objective lens, a sensing assembly, a driving assembly and a prism compartment positioned between the eyepiece and the objective lens. An interior of the prism compartment is provided with a prism bracket and a prism disposed on the prism bracket. The prism bracket includes a rotation frame, an inner rotation frame rotatably connected to the rotation frame, a control circuit board, and an inner shaft circuit board disposed on the inner rotation frame. The rotation frame is rotatably connected to a supporting shaft mount disposed within the prism compartment. The control circuit board is electrically connected to the inner shaft circuit board. The sensing assembly includes an outer Hall element, a sensing magnetic steel and an inner Hall element. The driving assembly includes an outer driving coil, a driving magnetic steel, and an inner driving coil.
