The Hotech SCA Laser Collimator is designed for astrophiles who want to align their Newton 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 or want to upgrade multiple telescopes.
What sets this collimator apart from all standard models is the patented SCA System (Self-Centering Adapter). Where cheaper laser tools often sit crooked in the focuser, this collimator automatically centers itself and eliminates any 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. At the rear is a 45° engraved aiming screen, allowing you to watch directly during adjustment - even if you are alone. The laser reflects back through the mirrors into the aiming window, allowing you to correct the alignment of the main mirror in real time.
The lightweight, CNC-machined aluminum design keeps your telescope 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 if you want to get it right the first time - regardless of whether you are a beginner or an advanced user.
