SVBONY SV121 1.25'" Laser Collimator for Newtorian and SCT
Precision Calibration Solution
Solves the problem of inaccurate telescope alignment with upgraded triangular screw structure that firmly locks the optical path, ensuring precise coaxial laser alignment and consistent, reliable calibration accuracy every time.
Enhanced Alignment Accuracy
Features a 45° aluminum scale plate with laser reflection for exact mirror alignment, delivering rounder, clearer laser spots (Class I laser, 0.1–0.5 mW output) and faster, more efficient telescope collimation, saving time on tedious adjustments.
Universal Compatibility & Easy Operation
Fits both refractor and reflector telescopes (especially Newtonian and SCT models) with a 1.25" interface, and comes with 3-level brightness adjustment to adapt to any lighting condition, enabling convenient alignment in both daylight and darkness.
Stable Connection & Durable Build
1.25" standard interface with dual 1.5mm rubber rings and micro-angle end compensates for manufacturing tolerances, eliminates gaps and wobble; all-metal body with sandblasted and anodized finish offers anti-corrosion, wear-resistant durability for long-term use.
User-Friendly Professional Design
Combines precision triangular screw light path locking, 45° scale plate alignment, and simplified brightness adjustment, plus wide compatibility with 1.25" telescopes (with optional 2" adapter) to meet the needs of both beginners and seasoned astronomers.
