Astronomy Plus Telescope Laser Collimator for 1.25 Inch or 2 Inch

Achieve precise and effortless collimation of your Newtonian or Dobsonian telescope with this laser collimator, designed to fit both 1.25-inch and 2-inch focusers. Whether you're a seasoned astronomer or just starting out, this tool simplifies the mirror alignment process and ensures optimal image sharpness at any magnification.

The collimator emits a bright, factory-aligned laser beam that reflects off your telescope’s mirrors, allowing you to quickly verify and adjust the optical path. The dual-size barrel ensures a snug and centered fit in both 1.25" and 2" focusers, minimizing misalignment caused by off-axis insertion.

Made from anodized aluminum, it offers a durable, lightweight body built to withstand regular use in the field or observatory. A target grid on the laser face helps visualize return beam accuracy, and collimation thumbscrews let you fine-tune the laser’s alignment if ever needed.

Ideal for quick checks or full collimation sessions, this laser collimator is the go-to tool for keeping your telescope’s optics in peak condition — so you can spend less time adjusting and more time observing.
