Description

Shop for Optic Accessories from Telescopes.com! HOTECH 2 Inch or 1.25 Inch SCA Laser Collimator2" SCA Laser Collimator for both Newtonian. Unit comes with one 1.25" SCA Laser Collimator with built-in Self-Centering Adapter pre-installed in a 2" to 1.25" SCA adapter and one CR123 battery.Ideal precision instrument to collimate your Newtonian. Unit comes with one patented 1.25" SCA Laser Collimator with built in Selft Centering Adapter pre-installed in a 2" to 1.25" SCA adapter and one CR123 batter and users manuals for Newtonian SCT and Star collimation.The HoTech laser collimator separates itself from all the other laser collimators with its innovative self-centering adapter technology (SCA). The mechanism allows precise and repeatable installation in all brands of 1.25" and 2" telescope focusers. All laser collimators in the current market have one fundamental problem - the 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 is no definite solution in the market yet.No matter how tight the tolerances are machined on the laser collimator or the focuser a small gap is required to allow installation of the laser collimator. Once the laser collimator is inserted the required gap becomes a problem. The laser collimator is fixed either with one or more thumbscrews or an unified compression ring. Both methods introduce a very critical issue namely an off-axis installment that instantly destroys the precision of your collimation instrument along the entire optical axis.The patented HoTech SCA Laser Collimator separates itself from all the other laser collimators with its innovative self-centering adapter technology (SCA).
