HOTECH’s SCA Laser Collimators

High quality laser collimators are hard to find
A time-saving astronomers tool

Give you more time for unforgettable Astro-images

Astronomy Products – Laser collimators are indispensable tools for aligning the optics of your time-machine-to-the-stars, but many laser collimators of the past had an inherent weakness in which the collimator wasn’t centered in the focuser. This often caused a small gap to exist between the collimator and the focuser’s drawtube, no matter how precise the machining of the collimator’s barrel. HOTECH’s SCA Laser Collimators have solved this problem using a Self-Centering Adapter (SCA) using rubber compression rings that expand evenly against the drawtube and center the collimator perfectly straight in the focuser.

Innovations in design and function

A clever idea that works by using three perfectly aligned laser beams to simulate the parallel rays coming from a distant star, HOTECH’s SCA Laser Collimators work great for quickly aligning the optics of your time-machine-to-the-stars. Stargazers using Ritchey-Chretien, Dall-Kirkham, Schmidt-Cassegrain, and Maksutov-Cassegrain telescopes can quickly, efficient and reliably prepare their telescope to continue their “Journey to the Beginning of Space and Time”, using the only effective method known to collimate their time-machines-to-the-stars.

HOTECH’s SCA Laser Collimators allow users to perform collimation indoors or outdoors, day or night, using a clear and simple to read display located within a short focal distance of the telescope for diagnosing alignment problems with a telescope optical systems without guess-work. Avoid the frustration of moving between the front and back of your telescope adjusting the corresponding alignment screw, while holding your breath and looking through a high magnification eyepiece trying to reference the concentricity of an image out of focus with HOTECH’s SCA Laser Collimators. You’ll have more time for viewing the universe and taking the unforgettable Astro images you really did all of this work for.

Astronomy telescopes are not all equal

Astronomy Products – Amateur astronomers during the past decade have had the opportunity to use moderately priced apochromatic refractors that just a few years ago were out of their price range. One of the finest 4-inch apochromatic refractors available for amateur astronomers, the 4.2-inch f/6.5 AT106LE from Astronomy Technologies combines outstanding optical performance thanks to a triple objective and engineering and design in tune with more expensive telescopes from a few years ago. Within the AT106LE, an FPL-53ED (Extra-low Dispersion) glass element decreases false color, while a dual-speed 2″ Crayford focuser, retractable dew shade and aluminum storage case complete the ensemble of a top-shelf telescope, without the sticker shock buyers normally associate with apochromatic refractors.
