Hotech 1.25"/2" SCA laser collimator - dot laser

The HoTech laser collimator stands apart with its revolutionary Self-Centering Adapter (SCA) technology. This mechanism ensures precise and consistent installation across all 1.25" and 2" telescope focusers, guaranteeing accurate collimation. Unlike traditional collimators, which often suffer from sloppiness in the adapting mechanism, the SCA cleverly eliminates this issue by employing expanding rubber rings. As these rings expand, they compensate for gaps, automatically centering the laser collimator in the focuser drawtube. This feature alone sets the HoTech SCA Laser Collimator ahead of its counterparts, ensuring dependable collimation every time.

Common Collimator Challenges Solved

Traditional collimators typically rely on thumbscrews or unified compression rings for securing, leading to inconsistent adaptation and alignment errors. The SCA, however, addresses these issues effectively:

• Eliminates Drawtube Slop: By expanding radially to fill gaps, the SCA ensures a firm and secure fit in the drawtube.
• Maintains Parallel Alignment: Its patented expanding o-rings design ensures solid 360-degree grip, keeping the laser perfectly parallel to the focuser.
• Stable Installation: Unlike traditional methods, the SCA adapts the collimator itself without relying on thumbscrews or compression rings, ensuring stability and precision.
• Accommodates Drawtube Imperfections: The rubber rings compensate for minor imperfections inside the drawtube, ensuring faithful centering of the collimator.
• Lightweight and Durable: Crafted from aerospace-grade aluminum, the SCA Laser Collimator combines durability with a lightweight design, preventing imbalance and structure sagging on your telescope.

Additional Features and Benefits

• Laser Engraved 45º Targeting Faceplate: Provides a clear visual reference during adjustment, allowing for easy alignment of the primary mirror from the rear of the telescope.
• Finest Projecting Laser Dot: Ensures precision collimation by limiting the laser beam to the optimal size for accurate visual effect.
• Proprietary Crosshair Laser Collimator: Offers enhanced precision during final collimation, guiding users with ease for accurate adjustments.
• High Accuracy Laser Alignment: Ensures the laser is precisely centered and aligned along the optical axis, critical for accurate collimation.
• Long Lasting Battery Life: With over 65 hours of continuous use, the CR123 3V lithium battery provides reliable performance even during extended observation sessions.
