Abstract
A variable power telescope with an automatic adjustment feature which enables the user of a firearm to automatically and quickly adjust the magnification power of the telescope while maintaining a secure grasp on the firearm with both hands and without losing the target viewed through the telescope. The magnification of the telescope is controlled through a battery-powered motor which can be operated by a switch near the trigger hand, allowing control with one finger on the user's trigger hand. The telescope also prevents operation of the motor beyond the adjustment range of the telescope by providing a shut-off switch that serves as a limit switch at the operational extremes of the telescope.
