Two facts: 1) You'll get the best images from a Newtonian reflector if its optics are in precise alignment, 2) a laser collimator virtually always results in a more precise optical alignment than a sight-tube collimator.

LaserMate takes the guesswork out of collimation, and your images will be sharper as a result. Especially for fast Newtonian systems of f/5 of lower, for which precise collimation is critical, LaserMate is essential.

It fits in a 1.25" focuser and emits a beam of red laser light into the telescope. The beam reflects off the secondary and primary mirrors and right back onto the bottom of LaserMate. If the beam hits the hole where it was emitted, the optics are in perfect alignment. If it misses, you just tweak the mirror angles until it hits. Easy as target practice!

LaserMate allows collimation to be performed in daylight or at night, whereas sight tube crosshairs are difficult to see in the dark. It's also more compact than most laser collimators: just 3" long. It takes up no more space in an accessory case than an eyepiece

LaserMate's housing is made of black-anodized aluminum.

Why pay $200+ for some laser collimators? LaserMate provides fast, pinpoint alignment every time. Weighs 5-1/2 oz. Instructions included. One-year limited warranty.
