Kendrick Laser collimation system. Works very well. Keeps your scope in perfect collimation. This is the 2" focuser model which fits in NGF-S Optec TCF-S and other 2" crayford type focusers. Especially useful when used with a Celestron Fastar system. Changing the secondary for the Fastar lens almost always messes up the collimation when you put the secondary back in. Also when adding collimation knobs etc save having to get a star back in the focus area to start collimating is a REAL CHORE with this you can put your collimation back close to perfect in a couple of minutes. Requires one time calibration routine. I never used the calibration just collimated inserted the laser collimator and put a sticky dot at the focus of the laser beam onto the face of the laser collimator. Screen is tilted to allow viewing of beam without exposing your eyes to the direct beam. Like to keep it but the wife won't allow me to buy a new camera until I sell off all my other stuff accumulated over the past 4 years. Fastar users this could save you a ruined night if you knock your secondary out of alignment. Heavy machined aluminum black anodized perfect condition no marks or scratches. Display area rulings are white and all are in perfect condition. All documentation also.
