Hotech SCA Laser Collimator 1.25 and 2 inch dot laser: collimating from a solid starting point<\/strong><\/h2>\n\n\n\n

If stars remain blurry while the sky is clear, then collimation is the first suspect. The Hotech SCA laser collimator aligns the mirrors of your Newtonian telescope quickly and reliably, with a principal advantage over standard laser collimators: the patented SCA system (Self-Centering Adapter).<\/p>\n\n\n\n

This version fits into both 1.25-inch and 2-inch focusers, making it the choice for those who own multiple telescopes or use a 2-inch focuser.<\/p>\n\n\n\n

Why SCA Makes a Difference<\/h4>\n\n\n\n

A standard laser collimator is secured with a set screw, causing it to tilt minimally in the focuser. This means the laser itself is already misaligned, and you are collating to an incorrect starting point. The SCA adapter secures the collimator with an expanding rubber ring, centering it precisely and perpendicularly. What you align afterward is truly accurate.<\/p>\n<\/div>\n<\/div>\n\n\n\n

That's how it works<\/h4>\n\n\n\n

Place the collimator in the focuser, point the laser dot via the secondary mirror to the center of the primary mirror, and then adjust the primary mirror until the beam returns onto itself. The entire process takes a few minutes after some practice and can be repeated each session.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Solidly executed<\/h4>\n\n\n\n

The laser is calibrated, the housing is made of metal and the bright red dot is also clearly visible on the mirror marking in the dark.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Featured accessories<\/h3>\n\n\n\n

A laser collimator is the first accessory for every Newtonian: collimation directly determines sharpness. Combine with stronger mirror springs for an adjustment that also stays put.<\/p>\n\n\n\n
