Orion 5684 LaserMate Pro Laser Collimation Kit

If you'd like a collimator that stands up to the rigors of real-life field astronomy, our new LaserMate Pro Heavy Duty collimation kit is for you. Even if you dropped it into your bag, don't worry. Did you accidentally bang it? No problem. This hardened design will guarantee the alignment of the collimating laser for a lifetime. Collimation is the process of the mechanical centering of your optics to give your telescope the best possible optical performance. If you own a Newtonian reflector (especially an assemble-on-site telescope) it needs to be checked every time you reassemble it. For tack-sharp images through some telescopes, you may even need to check alignment during your nighttime viewing session as well. With the LaserMate Pro, you'll get a lifetime of precise collimation so you'll enjoy the best possible visual and imaging experience to get the most out of your telescope. Achieve quick collimation with laser precision in a simple two-step process. First, insert the LaserMate Pro into a standard 1.25" eyepiece holder and adjust the secondary to center the red laser dot on the primary mirror. For 2" eyepiece holders, use a 1.25" to 2" expansion adaptor or Orion's Precision Centering Adapter for greatest accuracy. Then, use the included Cheshire eyepiece for final collimation by tilting the reflector's primary mirror. Illustrated instructions and centering dots are included. The LaserMate Pro is built of durable metal in gunmetal grey and has a lifetime guarantee!
