The Hotech SCA Laser Collimator is designed for astro enthusiasts who want to align their Newtonian telescope quickly and accurately, without compromising on precision. This version works in both 1.25 “and 2” focusers, making it the most versatile choice for those who own multiple telescopes or plan to upgrade.
What sets this collimator apart from all standard models is the patented SCA system (Self-Centering Adapter). Where cheaper laser tools often sit askew in the focuser, this collimator centers itself automatically and eliminates any form of play or tilt. No knurled screws. No compression rings. No guesswork – just reproducible precision.
The point laser projects an extremely fine and sharp dot, optimized for collimation at short distances within the telescope tube. On the rear is a 45° engraved targeting screen, allowing you to monitor during adjustment – even when working alone. The laser reflects back through the mirrors into the viewing window, enabling real-time correction of the primary mirror alignment.
Thanks to the lightweight, CNC-milled aluminum design, your telescope stays perfectly balanced. The collimator runs on a powerful 3V lithium battery and comes in a sturdy storage case, ready for years of use. This is the collimator you buy when you want to do it right from the start – whether you’re a beginner or an advanced user.
