The Farpoint Laser Collimator is the fastest, most repeatable way to align the optics on your Newtonian and Dobsonian reflector telescope. Drop it in the focuser, and the 650nm red beam shows you exactly where your secondary and primary mirrors are pointing — turning a fiddly, guess-and-check chore into a sixty-second routine you run before every session. Proudly made in the USA and backed by a lifetime alignment guarantee.
Machined as One Piece — Aligned for Life
Most laser collimators are assembled from separate parts, and every joint is a chance for the laser to drift out of true. Farpoint laser collimator bodies are precision-machined from a single piece of aluminum in one machining operation — there is no assembly seam to shift. The result is a collimator that arrives perfectly aligned and stays that way.
Backing that up is a superior eight-screw alignment system that locks both ends of the laser diode in place — not the single-point mount found on cheaper units. This is why every Farpoint laser carries a lifetime guarantee to never go out of alignment. Buy it once.
The Smallest Beam in Amateur Astronomy
Farpoint lasers produce a 0.76mm aperture beam — the smallest of any collimator on the amateur market. A tighter beam means less speckling and a far more precise reading of exactly where the dot lands on your primary mirror's center mark. When you are chasing tight star shapes, that precision is the difference between “close” and “collimated.”
Choose Your Barrel Size
Every Farpoint laser collimator ships with a protective carrying case and a bright, clearly visible 650nm red laser diode. Three configurations cover every focuser:
- 1.25" barrel — fits standard 1.25" focusers, the most common size on smaller and mid-size reflectors.
- 2" barrel — for 2" focusers, no adapter required.
- 1.25"/2" combo — a stepped barrel that drops straight into either focuser size, so one collimator covers every scope you own.
How to Use a Laser Collimator
Insert the laser into your focuser and turn it on. The beam first shows your secondary mirror alignment — adjust the secondary until the beam strikes the center mark of your primary. Then check the return beam: adjust the primary mirror until the reflected dot returns into the laser's target face. That gets your scope accurately aligned in about a minute.
For the final, most exacting primary alignment — and for fast imaging scopes — pair the laser with a Cheshire eyepiece and, if you image, an autocollimator. That complete two- and three-tool workflow, plus center-marking tools and bundled kits, lives on our main Telescope Collimation Tools page.
Why Collimation Matters
An uncollimated Newtonian shows elongated stars, reduced contrast, and soft planetary detail. Collimation aligns your primary and secondary mirrors so incoming light converges at a single focal point — the difference between a good view and a great one. A laser collimator makes that check fast enough to do every single time you set up.

Note: Farpoint laser collimators are designed for Newtonian and Dobsonian reflecting telescopes only. They are not intended for refractors, catadioptric, or SCT designs.
