Rowan Engineering timing belt set for Skywatcher HEQ5 Pro mounts

This kit replaces the factory spur gear drive train with timing belts. The pulley modification reduces the spur gear errors that are typical and therefore reduces tracking errors. The belts also make slewing much quieter eliminating the 'grinding' noise that the standard spur gears produce. The pulley ratio is the same as the factory gears. This means the Synscan hand controller is unaffected by this upgrade. All Synscanvfunctions will operate as before.
