Hotech Alignment Laser HyperStar Laser Collimator 14"
HyperStar 14" Laser Collimator: The simple and precise SC adjustment for HyperStar optics with 200mm aperture
Do you have a Schmidt-Cassegrain, Maksutov or RC telescope system? You are faced with the question: How do I adjust my telescope quickly and easily? It is best if the adjustment works very easily and still achieves a high level of accuracy. With an SC telescope, you can achieve a good optical image by regular adjustment.
Far and wide there's not a star in sight
With the clever HyperStar SC laser collimator you can adjust your Schmidt-Cassergarin telescope in no time with extremely high precision. You don't need a clear sky for that, you don't need a star for that. This adjustment unit from Hotech consists of a target into which three different lasers are embedded. Before adjustment, the disk is installed in front of the aperture of your telescope. The laser beams hit the main mirror, are reflected and hit the target again.
right on point
Leave your telescope on the mount. Adjust in the day or at night. Because when night falls, you are already well prepared. The adjustment is very simple and can be done by one person. You do not need a distance of 20 meters long. All you need is the laser collimator, a few meters of space, and the desire to have a perfectly aligned telescope.
The advantages at a glance:
Adjustment possible during the day.
no star needed for adjustment
can be done by one person
Fit within the focal length of the telescope
portable and easy to set up
Suitable for 14" (350mm) HyperStar SC telescopes
What is Hyperstar and how does it work?
Hyperstar is a multi-lens correction system that is used on the SC telescope's Schmidt correction plate in place of the normal secondary mirror. Coma and field curvature error correction of the primary mirror, which are normally corrected by the secondary mirror, is now performed by Hyperstar optics, which were calculated using the latest software. The CCD or DSLR camera is then attached to it at the front.
Result: Your standard Celestron SC telescope becomes a Schmidt design for your CCD or DSLR camera for prime focus photography at f/1.9.
Only now can the much higher efficiency of digital or CCD cameras dramatically increase the legendary performance of the Schmidt camera. No other combination will match it. Large-scale sky surveillance, soundings, comet observations, and normal deep-sky photography can be made much more efficient with the digital Schmidt camera.
In 30 seconds of exposure time you get the same brightness as after about 12 minutes at f/10. Exposure times are thus reduced by a factor of about 25. Blurring caused by air turbulence or tracking errors no longer occurs.
Therefore, the image is sharper overall. Also, the use of an equatorial mount is no longer absolutely necessary. With an exposure time of just 30 seconds, there is no field rotation effect, which makes long exposures with azimuth mounts impossible. You can take multiple series of shots, and then overlay the shots during post-processing for great deep-sky images with little effort.
We offer Hyperstar lens kits for C6, C8, C925, C11 and C14 lenses.
Prerequisite: The Schmidt plate of the SC telescopes must have the FastStar connection. This is already the case with Celestron's new SC optics. However, we also offer conversion kits (item no. 16371, 16372, 16373) that make Hyperstar telescopes compatible.
If the Schmidt plate is equipped with FastStar, the secondary mirror is simply unscrewed and the Hyperstar optic is screwed on with an adapter ring. There is also no conversion kit required for EdgeHD optics.
Some advantages of the Hyperstar optics at a glance:
transforms your "old" Celestron SC telescope into a digital Schmidt camera (while maintaining its use as standard SC optics)
No problem with primary mirror change
Allows an extreme reduction of exposure times
Dramatically simplified tracking, even with simple azimuth tracking, the highest quality astrophotography is possible.
No fine adjustment of the poles is necessary in mobile operation, as there is no drift in declination due to extremely short exposure times
Light intensity and field size favor astrophotography with narrowband line filters
DSLR cameras work best at f/2 as they rely on fast aperture rates due to their design
Hyperstar FAQ:
Question: How do you focus when shooting with Hyperstar optics?
Answer: Very normally through Can I also visually observe through the Hyperstar optics?
Answer: No, because the observer's head is then facing the Schmidplatte. The obstruction would be huge.
Question: How annoying is the mirror shift when focusing?
Answer: Removing the secondary mirror removes the 5x magnification of an f/10 SC system. This means that the mirror shift also has a 5x smaller effect. Mirror change is no longer a problem.
Question: How good is the image quality?
Answer: The quality is comparable to that of an astrophotographic RC system, the resolution is adjusted even for semi-professional cameras like the ST-10 from SBIG. The stars are much finer than at f10.
Question: Isn't the obstruction caused by the camera disturbing?
Answer: Obstruction is not as critical for photographic applications as it is for visual observation. Therefore, for example, almost all professional reflector telescopes with a diameter of several meters have a significantly higher obstruction than an SC with Hyperstar and DSLR.
Question: What about the collimation of the Hyperstar optics?
Answer: Hyperstar optics are collimated once the first time they are used. Changing the Hyperstar back to the standard version requires no relimation because the normal secondary mirror unscrews and then screws back on as a complete fitted unit.
Question: Are there any downsides to using Hyperstar optics?
Answer: Yes, you don't want to go to bed on a clear, moonless night.
Hyperstar optics are the fastest and easiest way to capture deep sky images. No polar adjustment, no equatorial mount, no guide. Hyperstar turns any 8"/11"/14" Celestron SC telescope into an ultra-fast digital Schmidt camera. Deep sky imaging takes seconds instead of hours - astrophotography has never been easier!
