The Deluxe models are a Saddle/Plate system. The scope requires a male dovetail mounting plate (or rail) attached to it and can then attach to the Deluxe Head which has a female dovetail saddle design. This allows for quick installation and removal of the optics, as well as allows for balancing the optics for and aft. The amount of travel for balance is dependent on the length of the mounting plate. The UniStar Light and MicroStar Deluxe heads hold the plate with a single clamping knob and is designed to hold rails from 1.5-2.25" wide. This includes Vixen, Orion, Celestron, Meade (these are all Synta rails from China), Astro-Physics, etc, and our own 2" saddle plate.
