The same motor can be used to provide up down movement on a hunting bow. Use a laser range finder to calibrate with a look-up table how many mm up the sight must move for increasing distance. These values are stored in a micro processor. Use a tunable pot resistor with display led to range between 1 and 99m , the input of which is fed to an AtmelMicro which in turn positions the Parker Daedal servo motor. A inertial rate gyro RateGyro2 compensates for the angle at which the bow is held with the values also stored in a look-up table for a specific bow, draw-length, kinetic energy and draw weight. Shooting at an angle of 45degrees to a target on top of a mountain at the same distance as holding the bow level will not result in the linear servo motor, enacting the same scaling hence the need to compensate for the angle using a rate gyro. 
=== Band pass filter ===
Edmund Optics - http://www.edmundoptics.com/onlinecatalog/browse.cfm?categoryid=10 - DWDM dielectric bandpass filter, is also used in the optical path to allow only predetermined optical wavelengths to pass through.
=== Sights ===
Hunt by placing bow on tripod for stability.
