Alstar 1.25" Laser Collimator For Newtonian Telescopes - Red Laser Alignment Tool

About This Product

Telescope owners, this Alstar laser collimator makes aligning your Newtonian reflector so much easier than those old-fashioned Cheshire eyepieces!

The 1.25-inch diameter fits standard focusers, and the red laser beam (635-655nm wavelength, under 5mW power) gives you a precise reference point for perfect alignment.

Instead of constantly moving between the eyepiece and adjustment screws, you just look at the laser target and adjust until the red dot centers - it's that simple.

The metal construction feels substantial and durable, with three adjustment ports arranged at 120 degrees for fine-tuning if needed (though it comes pre-adjusted from the factory).

It runs on one CR2032 battery (not included - the same type used in watches and small electronics) that's easily replaced by unscrewing the knurled cap.

The side window with 45-degree angled disk lets you verify the return beam for secondary mirror alignment.

Even if you're new to telescope collimation, the included German and English instructions walk you through the process step-by-step.

Proper collimation means sharper planetary details, cleaner star images, and getting the most out of your telescope's optics.

Just remember laser safety - never point it at eyes or skin!

This tool turns a frustrating chore into a quick 5-minute task.
