QUIETEYE Gyro-stabilized telescope with “Near-focus image stabilization” Gyro-stablization is based on the principle of conservation of angular momentum. The gyro consists of a motor and a flywheel which, when spinning at full speed, resists changes to its orientation due to the angular momentum of the flywheel. When the unit shakes in one direction, the gyro moves in the opposite direction. Through manipulation of the prisms, gyro-stabilization provides a pure image. The small amount ofmovement when holding a telescope, called “jitter,” is magnified by the optics, degrading the image. In a gyro-stabilized telescope, the prisms are mounted on a platform (gimbal) that can swivel independently of the rest of the telescope. A small motor driven gyroscope sits on the platform manipulating the prisms to stabilize the image and retain clarity.
