HoTech 8" HyperStar Laser Collimator
This fast and precise device takes the Hyperstar up yet another level of quality. The HOTECH Hyperstar Laser Collimator let's you collimate your Hyperstar enhanced telescope without needing a star- and that's just the tip of the metaphorical iceberg! It also permits you to collimate indoors at your final view setting without taking up your precious observing time, and allows you to achieve complete optical train alignment using one device. All of this and more can be accomplished with this new device! In order to achieve an accurate star collimation, normally the amateur astronomer requires good seeing conditions with no cloud, no wind, stable temperature, no light pollution, a well-aligned telescope mount tracking system, telescope optical tube assemble (OTA) thermal equilibrium, and a good visible magnitude star. The visual quality of the referencing star is greatly affected by the prescribed factors most of which are all in natures hands, generally beyond control. Adjusting the collimation is guessing game where you move between front and the back of the telescope adjusting the corresponding alignment screw and holding your breath peeping through a high magnification eyepiece referencing the concentricity of the unstable defocused image. This can be an incredibly frustrating experience- but no more with the HyperStar Laser Collimator! With the HyperStar Laser Collimator, you can accurately collimate using an artifical star without need for long distance. To rephrase, the HyperStar Laser Collimator does not require long distances to achieve high-accuracy collimation. Utilizing the installed flat mirror at the focal point (imaging sensor location), the collimator lasers double-passes the optical train and magnifies the alignment errors to a higher accuracy level. In addition, it also cuts the collimating distance in half achieving near-field alignment process. The collimator is stationed within your telescope's focal length directly in front of your telescope. Setting up for collimation, you will be standing between the telescope and the collimator aiming both the telescope and the collimator at each other. Then you will adjust the HyperStar collimation knobs to bring the returning lasers on the same track. This is a very convenient one-man-operation collimation task. To make a long story short, the HyperStar Laser Collimator makes an otherwise lengthy and difficult task easy and relatively convenient, removing the need for many frustrating steps and the reliance on natures whims that plagues more traditional collimation procedures. It also aids greatly in several other procedures! The HyperStar Laser Collimator can be relied on in the following two procedures fully in addition to laser Collimation;
- Corrects the optical axial tilt between the HyperStar focal plane and the primary optical axis.
- This process keeps the focal plane orthogonal to the primary optical axis so the captured image will be in-focus from corner to corner.
- Corrects the centration error between the HyperStar optical axis and the primary optical axis.
- This process centers the focal point to the precise center of the imaging sensor for maximum collimated FOV capture.
The HyperStar Laser Collimator is also a highly efficient choice, performing the same rough alignment function of a costly large aperture interferometer commonly used in high-energy labs at a fraction of the cost! Your HyperStar Laser Collimator uses three collimated lasers, evenly spaced apart, to sample large aperture optical elements in your telescope. The three parallel laser beams completely simulate the light path (flat-wavefront) from a distant star and pass through the entire telescopes optical elements and reflect back to its target for a complete and accurate double-pass diagnostic reading of your telescope optical alignment. This innovative collimation technique and technology enables the amateur astronomer achieving far-field collimation as a near-field process. Finally, your HyperStar Laser Collimator will be precision CNC machined from a solid block of aero-space grade aluminum. It is then hardened and anodized to keep the entire mounted laser system thermally stable allowing you to achieve accurate collimation. The rigid, ultra thin profile, and light-weight design makes the unit portable and simple to setup and use. The final word is simple; the HyperStar Laser Collimator is a simply excellent piece of hardware, a splendid choice for any astronomer with a scope that needs collimation! This particular model is sized for 8" Hyperstar enhanced telescopes, and only for those size aperture scopes. Manufacturer Product Number: HLC-800
