A telescope collimator is a device used to align the optical elements of a telescope, such as mirrors or lenses, to ensure that the light passing through them is focused properly. Collimation is an essential process for maintaining the performance and accuracy of a telescope.

This laser Collimator is specifically designed for Reflector telescopes and comes with a removable 2″ adapter that fits both standard 1.25 inch and 2 inch diameter eyepieces. It features a red laser collimation beam with 7 brightness levels and a wavelength of 635-655 nm, with an output power of less than 5mw, making it much safer for your eyes. With this sturdy laser unit, you can easily and precisely collimate your Newtonian telescope, allowing you to experience its full performance potential.

Made of durable metal material, this laser unit requires a CR2032 Lithium Cell battery (not included) and provides accurate collimation in just a few minutes, resulting in a clearer image. The telescope can be collimated by just one person, making it easy to use. The precision-made aluminum housing of the laser unit has a front opening for emitting the laser beam, and a side window that allows you to view a 45° oriented disk with a central hole. This feature allows you to see if the laser is reflected back on itself, indicating well-collimated optics.

This adjustment tool can be used in all 1.25″ focusers, and we provide precise instructions in both German and English, with a step-by-step explanation of how to adjust a Newtonian telescope using this laser unit. Even if you are new to amateur astronomy, you can easily get the most out of your telescope’s performance.

The laser unit comes fully adjusted but can be further adjusted if needed, with three openings for adjustment arranged at 120°, which are initially sealed. The battery can be replaced at any time by unscrewing the small cap at the rear of the laser.
