Laser Collimator · 1.25"
Fast, accurate secondary alignment and a quick primary check — the essential first step in Newtonian collimation.
The Farpoint 650nm Laser Collimator with 1.25" barrel is our most popular standalone model, designed for Newtonian and Dobsonian reflectors with standard 1.25" focuser drawtubes. Every Farpoint laser collimator body is machined from a single piece of aluminum in one machining step — not assembled from separate parts — ensuring perfect concentricity from the factory. The superior eight-screw alignment system locks both ends of the laser diode in place with two sets of directly opposing screws, delivering precise and lasting alignment that cheaper three-screw designs can't match. Precision-machined in the USA with a lifetime alignment guarantee.
Specifications
Beam aperture
0.76mm (30/1000") — the smallest of any collimator on the amateur astronomy market, producing less speckling and more precise readings
Laser
Extra-bright 650nm red laser for clear visibility in all conditions
Barrel
1.25" stepped barrel — fits standard focuser drawtubes on most Newtonians and Dobsonians
Body
Rugged red anodized aluminum — red finish best shows the position of the laser return beam
Switch
Protected switch with positive action, shielded by an aluminum ring to prevent accidental power cycling
Build
Machined from a single piece of aluminum in one machining step; eight-screw alignment system; made in the USA; lifetime alignment guarantee
In the box
Laser collimator, mirror center-marking template and triangle center spots (standard template works with mirrors up to 12.5"; large templates available separately), and carrying case
For
Newtonian and Dobsonian reflectors only — not for refractors, catadioptric, or SCT designs
Where it fits in the workflow
Laser (this tool)→Cheshire→Autocollimator
The laser gives you accurate secondary mirror alignment and gets the primary into the ballpark quickly — the essential first step. A Cheshire then delivers final, precise primary alignment, and an autocollimator refines it further.

Complete the two-tool workflow. For final primary mirror alignment, pair this laser with a Farpoint 1.25" Cheshire eyepiece. Want both in one package? Our 1.25" Collimation Kit bundles a laser, Cheshire, and center-marking kit in a carrying case. Need a 2" barrel option? See the 1.25"/2" combo model.
Frequently Asked Questions
Will this laser collimator work on my SCT or refractor?
No. The Farpoint laser collimator is designed for Newtonian and Dobsonian reflecting telescopes only. It is not intended for refractors, catadioptric, or SCT designs.
Why does the 0.76mm beam aperture matter?
At 0.76mm (30/1000 of an inch), this is the smallest aperture of any collimator on the amateur astronomy market. A smaller aperture produces less speckling and a dramatically more precise reading of the beam's position on your primary mirror.
What makes the eight-screw alignment better than three-screw designs?
The eight-screw system locks both ends of the laser diode in place with two sets of directly opposing screws. This holds alignment precisely and lastingly, something cheaper three-screw designs cannot match. Every body is also machined from a single piece of aluminum in one machining step for perfect concentricity.
Do I still need a Cheshire if I have this laser?
For best results, yes. A laser gives you accurate secondary mirror alignment and gets the primary into the ballpark. For final, precise primary mirror alignment, pair it with a Cheshire eyepiece. This two-tool approach is widely regarded as the gold standard for Newtonian collimation.
