Discover the HyperStar Laser Collimator: Your Telescope's Must-Have Accessory.
Unlock a new era in HyperStar telescope collimation with our fast and precise laser collimator. This patented technology takes HyperStar collimation to an entirely new level, making it an indispensable addition for every telescope owner.
Here's why the HyperStar Laser Collimator is a game-changer:
1. Starless Precision: Achieve pinpoint accuracy in collimation without relying on a star. Say goodbye to the constraints of star-dependent collimation.
2. Indoor Convenience: With the HyperStar Laser Collimator, you can collimate your telescope indoors, right at your final view setting. No need to sacrifice your valuable observing time or wait for perfect outdoor conditions.
3. All-in-One Alignment: This ingenious device ensures complete optical train alignment with just one tool. It simplifies the collimation process, making it accessible to all telescope enthusiasts.
Make the HyperStar Laser Collimator an essential part of your telescope equipment, and experience effortless, precise collimation like never before.
Accurate Collimation without using a Star
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 Gods hand as you can see in the photo. 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.
An artificial star can never faithfully replicate a real star due to the inherent limitation of collimating a telescope with its focus set at infinity. Following the collimation with an artificial star, a subsequent adjustment is required to return the telescope's focus to infinity for viewing actual celestial objects. This necessitates moving the primary mirror to a different focal position, which may accumulate mechanical tolerance errors over time.
In certain mass-produced Schmidt-Cassegrain telescopes (SCTs), issues like the 'sticky baffle' in the primary mirror focusing mechanism can introduce the potential for mirror-flop. If mirror-flop occurs, it disrupts the alignment, rendering the prior collimation efforts ineffective. Ideally, the best practice is to perform collimation of your optics at the same focusing position used for actual observations, minimizing optical displacements and potential errors.
The HyperStar Laser Collimator is a valuable tool in this regard, ensuring precise collimation without introducing unnecessary accumulated errors, resulting in an optimal viewing experience.
Collimate with Precision at Final View Setting in Short Distance
The HyperStar Laser Collimator offers the advantage of achieving pinpoint accuracy in collimation without requiring extensive distances. By strategically positioning the collimator with an installed flat mirror at the focal point (the location of the imaging sensor), it ingeniously enables the laser to perform a double pass through the optical train. This process effectively magnifies any alignment errors, elevating the accuracy of the collimation to impressive levels.
Moreover, this innovative approach significantly reduces the required collimating distance, cutting it in half. The result is a near-field alignment process that simplifies and streamlines the collimation task. The HyperStar Laser Collimator is positioned conveniently within your telescope's focal length, right in front of the telescope.
During the collimation, you'll find yourself standing between the telescope and the collimator, aligning both with precision. Adjusting the HyperStar collimation knobs allows you to bring the returning lasers onto the same track. This one-man-operation collimation task is not only highly accurate but also incredibly convenient.
Complete Final Optical Train Alignment with one device
The HyperStar Laser Collimator identifies and assists the user to align the following parameters:
- 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.
At a Fraction of the Cost of the Wavefront Interferometer Technology
The
state-of-the-art advanced laser optical alignment technology used in
the HyperStar Laser Collimator achieves the same rough alignment
function of a costly large aperture interferometer commonly use in
high-energy labs at a fraction of its cost.
The
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
telescope’s 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.
Precision CNC Machined Panel and Components
This beautifully designed instrument is precision 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.
Upgrade Kit Available for ACT Laser Collimator Owners
For users already purchased the Advanced CT Laser Collimator, you may purchase the corresponding Upgrade Kit without purchasing the laser unit. The Kit will include the proper sized HyperStar adapter and the new developed dual-sided reflector mirror for your convenience.
