Product Description

   
Founded in 2002, HOTECH is a leading company in the opto-electronic industry serving the Astronomy community the world over. Throughout the history of HOTECH USA, the company has continuously brought forward innovative and proprietary technologies to develop state-of-the-art, next-generation optical products offering a competitive edge to Astronomers everywhere.  Enter the HOTECH Advanced CT Laser Collimator, HOTECH's latest device to improve visual accuracy in the Schmidt-Cassegrain telescope and designed to replace the much more complicated and costly Wavefront Interferometers as collimation tools for larger aperture reflectors.

The HOTECH Advanced CT Laser Collimator samples the entire optical system (primary, secondary mirror, and eyepiece axial position) with a simulated large aperture flat-wavefront light source generated by three parallel lasers positioned behind the supplied Target Plate.  By using three perfectly aligned laser beams it emulates the parallel rays coming from a distant star. The beams then pass through the telescope twice to magnify any error in the entire system.  Because of this redundancy even tiny collimation errors become apparent and can then be corrected.

The only user accessible collimation alignment point on a Schmidt-Cassegrain Telescope is via the (3) secondary mirror alignment screws located behind the secondary mirror at the front of the Telescope  Therefore, you only need to adjust the three alignment screws to adjust the secondary mirror to move the three laser spots onto the same circle on the target plate. This limited adjustment makes the collimation simple to perform. The target plate provides a clear view of the mirror alignment when the three lasers are reflected back on the target. The Target Plate should be held in place at the appropriate height by the included adjustable tripod head. Finally, the appropriate  * Reflector Mirror (1¼" or 2" - your choice depending on the size of your focuser) is inserted in the Visual Back (imaging) or into the Diagonal (visual use) on the Scope. That's it. Start Collimating!

    * This Package includes BOTH  1¼ " and 2"  Reflector Mirrors for your convenience *

If a user has any questions about the setup process, the ACT Laser Collimator comes with a well illustrated and written Owner's Guide, 7 pages in length which will definitely clear up any confusion during initial setup.  ALSO,  watch the 2 videos below which will take you step by step thru the Collimation Process with the Advanced CT Laser Collimator.
