Starizona HyperStar V4 for Celestron C6 SC telescope with adapter

Starizona HyperStar V4 for Celestron C6 SC Telescope with Adapter


The HyperStar turns your Celestron C6 Schmidt Cassegrain into a fast 150 mm f/2 CCD telescope for astrophotography.
♦ Suitable for all Celestron C6 Schmidt Cassegrain telescopes - every C6 is FastStar suitable

♦ The 150 mm f/10 SC system becomes a fast CCD astrograph with 290 mm focal length and f/2 aperture ratio

♦ The Hyperstar system is used instead of the secondary mirror

♦ Focusing is still done via the main mirror of the telescope

♦ Due to f/2, the exposure times become so short that autoguiding can be dispensed with

♦ Distance to camera sensor: 39.8 mm from the top edge of the Hyperstar (without external thread) or 44.3 mm including external thread (identical to Hyperstar for C8)

♦ Illuminated and corrected field of view - 28 mm diameter.

♦ The Hyperstar for C6 is only suitable for astro cameras, SLR cameras have too long a working distance.

Starizona Hyperstar adapter for astrophotography with Celestron SC and EHD telescopes.
With the Hyperstar you can transform your Schmidt-Cassegrain or EdgeHD telescope from Celestron into a fast astrograph. Astrophotography becomes an experience and has never been easier. Within 30 seconds, thanks to the Hyperstar, you will achieve a comparable result as without the Hyperstar after more than 12 minutes. This increases the efficiency of your camera and telescope many times over. In just one night, you will achieve a depth of field for which you previously needed many nights. Blurring due to air turbulence or tracking errors are also a thing of the past. The image will be sharper overall with less effort.

How to mount the Hyperstar to your Schmidt-Cassegrain:
Carefully unscrew the secondary mirror from the mount. Avoid twisting the Schmidt plate or the secondary mirror mount in the Schmidt plate. Then simply screw the Hyperstar into the thread and the conversion is complete.

FAQs about the Hyperstar:

♦ Question: How is focusing done when photographing with the Hyperstar optics?
Answer: Quite normally via the main mirror, as in the standard version.

♦ Question: Can I also observe visually through the Hyperstar optics?
Answer: No, because the observer's head is then BEFORE the Schmid plate. The obstruction would be huge.

♦ Question: How annoying is the mirror shifting during focusing?
Answer: By having the secondary mirror removed, the 5x magnification of an f/10 SC system is eliminated. This means that mirror shifting also has 5 times less of an effect. Mirror shifting is no longer a problem as a result.

♦ Question: How good is the imaging quality?
Answer: The quality is comparable to that of an astrophotographic RC system, the resolution is adapted even for semi-professional cameras like the ST-10 from SBIG. The stars are much finer than with f/10.

♦ Question: Is the obstruction by the camera not disturbing?
Answer: Obstruction is not as critical for photographic applications as it is for visual observation. Therefore, for example, almost all professional reflecting telescopes with several meters diameter have a much larger obstruction than a SC with hyperstar and DSLR.

♦ Question: What about the collimation of the hyperstar optics?
Answer: The Hyperstar optic is collimated once the first time it is used. Changing the Hyperstar back to the standard version does not require re-collimation because the nominal secondary mirror is screwed out as an adjusted complete unit and then screwed back in again.

♦ Question: Are there any disadvantages to using the Hyperstar optics?
Answer: Yes, you will not want to go to bed on clear moonless nights.
