Align your optics with a precision laser collimator. An absolute must-have for Aspheric system performance. This laser collimator boasts some of the best and most highly practical functions collimators can offer. Lighter than most other brand name collimators, Antare's LC is made of lightweight aluminum which fits on a 1.25" focuser. A large display window allows the user to clearly see the face of the device. Where most other brand name collimators only have one setting, Antare's LC has seven adjustable brightness levels.
