The LaserMate Deluxe II Laser Collimator by Orion: With the LaserMate Deluxe II Laser Collimator, you will get dead-on alignment (a.k.a., collimation) of your reflector telescope's primary and secondary mirrors quickly and consistently. Its "rear-view" port has a bulls-eye target that lets you adjust your telescope's primary mirror while conveniently standing at the rear of the telescope, where the primary mirror adjustment screws are located. You just adjust the collimation knobs until the laser beam's red dot hits the bulls-eye, and then you are done and your telescope's optics are aligned! This second-generation LaserMate Deluxe features an improved, all-aluminum housing with a wider, 3 mm barrel flange to ensure that the collimator seats squarely in the telescope's eyepiece holder - exactly parallel to the focuser's mechanical axis. This optimized housing design, combined with the highly accurate factory-set alignment of the laser within the housing, results in consistent pinpoint collimation with every use! Your properly collimated reflector telescope will serve up the sharpest, clearest views possible, night after night. The LaserMate Deluxe II is ideal for use with any Newtonian reflector telescope, including Dobsonian reflectors and Newtonian astrographs. It works especially well on telescopes with focal ratios of
