1.25-Inch Red Laser Telescope Collimator with Adapter

Make mirror alignment part of your Newtonian telescope setup. This red laser collimator fits a 1.25-inch eyepiece holder and includes a 2-inch adapter, providing a visible reference while you follow the telescope's collimation procedure.

✅ See an alignment reference - The red laser provides a visible point for the collimation procedure.

✅ Use two focuser sizes - The removable adapter converts the 1.25-inch barrel for a compatible 2-inch holder.

✅ Adjust the dot brightness - Seven intensity levels let you set the laser for the viewing conditions.

Check Alignment Before the Observing Session

When a reflector is moved or set up again, checking its alignment is a useful preparation step. A collimator provides a reference for that process, letting you address the optical setup before spending time at the eyepiece.

Seat the collimator squarely and follow the telescope manufacturer's adjustment method. Confirm the collimator's own alignment, and keep the beam away from eyes and reflective paths. The adapter changes the barrel fit; it does not make every telescope design use the same procedure.
