Ideal precision instrument to collimate your Newtonian and SCT telescope. The HoTech unit comes with one patented 2" SCA Laser Collimator w/ built-in Self-Centering Adapter, one CR123 battery, and users manuals for Newtonian, SCT, and Star collimation.
The HoTech laser collimator separates itself from all other laser collimators with its innovative self-centering adapter technology (SCA) . This mechanism allows precise and repeatable installation in all brands of 1.25" and 2" telescope focusers thus provides accurate collimation. All laser collimators in the current market have one fundamental problem, slop in the adapting mechanism between the laser collimator and the telescope focuser. This problem is clearly recognized and often discussed among astronomers but so far there has been no definite solution in the market.
