Farpoint 650nm Laser Collimator - 1.25 Inch

The Farpoint 650nm Laser Collimator with 1.25" barrel — our most popular standalone model, designed for Newtonian and Dobsonian reflectors with standard 1.25" focuser drawtubes. Precision-machined in the USA with a lifetime alignment guarantee. Includes carrying case. For Newtonian and Dobsonian reflectors only.

Why This Laser Collimator Is Different

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. Our superior eight-screw alignment system locks both ends of the laser diode in place with directly opposing screws, delivering precise and lasting alignment that cheaper three-screw designs can't match.

Key Features

• 0.76mm beam aperture — the smallest of any collimator on the amateur astronomy market, producing less speckling and dramatically more precise readings on your primary mirror
• Extra-bright 650nm red laser for clear visibility in all conditions
• 1.25" stepped barrel — fits standard focuser drawtubes on most Newtonians and Dobsonians
• Rugged red anodized body — red finish best shows the position of the laser return beam for easier alignment
• Protected switch with positive action, shielded by an aluminum ring to prevent accidental power cycling
• Includes mirror center-marking template and triangle center spots (standard template works with mirrors up to 12.5" — large templates available separately)
• Carrying case — keeps your collimator protected in transit

The First Step in the Two-Tool Workflow

A laser collimator gives you an accurate secondary mirror alignment and gets your primary into the ballpark quickly — the essential first step. For final, precise primary mirror alignment, pair this laser with a Farpoint 1.25" Cheshire eyepiece. This two-tool approach is widely regarded as the gold standard for Newtonian collimation.

Want both tools in one package? Our 1.25" Collimation Kit bundles a laser with a Cheshire and center-marking kit in a carrying case. Need a 2" barrel option? Check out our 1.25"/2" combo model.
