Engineered for Accuracy & Durability

This professional-grade laser collimator features:

• Long 1.25-inch barrel for secure, stable seating in any standard focuser

• CNC-machined rim and components for exceptional mechanical precision

• New 45° angled viewing port for effortless collimation from the rear of the telescope

• Strong anodized aluminum body, built for long-term durability

• Three LR44 batteries included, ready to use out of the box

Each element is carefully machined to maintain strict tolerances, giving you a dependable alignment tool trusted by amateur astronomers and observatories across India.

Easy Collimation Workflow

Using the laser collimator is simple and intuitive:

1. Insert the collimator into your 1.25" focuser (or 2" focuser using a 1.25" adapter).

2. Adjust the secondary mirror until the projected laser dot lands precisely at the center of the primary mirror’s marked spot.

3. Tilt the primary mirror so the returning laser beam aligns perfectly with the target on the collimator.

4. Check at both high and low focuser positions to verify consistent alignment.

This ensures your optics are perfectly aligned for crisp lunar views, deep-sky clarity, and high-magnification planetary detail.
