If stars remain blurry or planetary details disappoint while the sky is clear, chances are your telescope isn’t properly collimated. The Hotech SCA Laser Collimator 1.25 inch is the right tool: reliable, precise, and designed for both visual and practical users.
Unlike standard laser collimators that can have play in the focuser, Hotech uses a patented SCA (Self-Centering Adapter). This ensures the laser is always exactly centered, without screws or loose fitting. This prevents tilt, and thus incorrect alignment.
What makes this version extra special is the integrated 45° targeting screen on the back. This allows solo observers to perform collimation alone: while working at the back of your telescope, you can look directly at the screen and see exactly where the laser returns on the primary mirror. The laser point is displayed on a finely engraved reticle, making centering quick and intuitive.
The robust aluminum housing, sharp laser projection, and included sturdy storage case make this an investment that will last for years. Compatible with any 1.25″ focuser – from small reflectors to serious Dobsonians.
