Collimation in a telescope is essential to obtain maximum performance, the best method is a high magnification star test but often you do not have the time or the right knowledge to perform it correctly. A valid help for the amateur astronomer are the laser collimators that guarantee a good collimation, in many cases, however, due to an economical construction, they cannot guarantee adequate accuracy.

Why Hotech collimators are different:

• Unlike the other collimators which are blocked and offset by the screw of the eyepiece holder, the SCA collimator is self-centered thanks to a rubber membrane that expands by turning a ring nut
• The laser is centered in the collimator body with extreme precision
• They are very light to prevent the weight from tilting the laser body
• The reticle on the 45 ° face is embossed to ensure greater visibility
• Quality lasers are used, with a powerful but very small and concentrated beam
• No button cell batteries, a 3v lithium CR123 battery is included in the package to ensure long life.
• Each laser is delivered in an elegant box
• Can be used on Newtonian and SC telescopes

Crosshair model:

The crosshair model in addition to having the red laser dot has 4 lines that help both to better center the secondary (for example at night), and the primary on the 45 ° notch of the laser, especially when it is very unglued
