Only selling due to ill health, C14 V3 Hyperstar with ZWO Filter Draw and the correct spacers to fit a ZWO camera. There is also an adapter to fit a ZWO Mini Filter wheel (not included) should you want to automate monochrome imaging or narrowband imaging. The Mini Filter wheel doesn’t obstruct the light path enough to be noticeable; it’s about the same obstruction as using an SLR. There is also a Nikon adapter for an SLR. Image circle is 27mm, ideal for APS-C size sensors; I was using a ZWO ASI2600MC.
Comes with a carry case.
I was using this Hyperstar on a 16 inch Meade LX600.
A Hyperstar landed in Australia costs over $2500.
PRICE $1200 Posted

Manufacturers Description
Starizona Hyperstar Adapter for Astrophotography with Celestron SC and EHD Telescopes
With the Hyperstar you turn your Schmidt-Cassegrain or EdgeHD telescope from Celestron into a fast astrograph. Thus astrophotography becomes an experience and has never been easier. Thanks to the Hyperstar, you need only 30 seconds to achieve a result compareable to more than 12 minutes without Hyperstar. With this, you increase the efficiency of your camera and your telescope many times over. In just one night you reach an exposure depth for which you would have needed many nights in the past. Blurring due to seeing or guiding errors also are a thing of the past. The image becomes sharper in general with less effort.
How is the Hyperstar mounted to your Schmidt-Cassegrain:
Unscrew the secondary mirror carefully out of its holder. Avoid that the Schmidt plate or the holder in it is turned out of position. Then just screw the Hyperstar into the thread and you are already ready with retrofitting.
The manufacturer offers various information about the HyperStar on its Tutorial Pages, including:
♦ compatible equipment
♦ current specs (though the pdf links are dead)
♦ detailed installation guide
♦ Example instructions for telescopes without polar wedge

FAQs concerning Hyperstar:
♦ Question: how is focusing done when photographing with the Hyperstar optics?
Answer: with the main mirror, as before.
♦ Question: can HyperStar be used for visual observation?
Answer: no, as the observer´s head would be placed BEFORE the Schmidt plate. The obstruction would be gigantic.
♦ Question: how disturbing would be mirror shifting when focusing?
Answer: due to removing the secondary mirror, the 5x magnification of the f/10 Cassegrain system also does not apply. This means that mirror shifting is reduced to one fifth, too. For this reason mirror shifting is not a problem anymore.
♦ Question: how good is the image quality?
Answer: the quality is compareable with the one of an astrophotographic RC system, the resolution is sufficent even for semi-professional cameras like the ST-10 from SBIG. The stars are significantly smaller than with f/10 or f/11.
♦ Question: isn´t the obstruction of the camera disturbing?
Answer: obstruction is not as critical for photographic purposes as for visual observing. Therefore, for example, all professional reflector telescopes with several metres diameter have a clearly larger obstruction than an SC with Hyperstar and DSLR.
♦ Question: what about collimating the Hyperstar optics?
Answer: the Hyperstar optics is collimated once at the first use. Switching back from the Hyperstar to the standard version does not require new collimation, as the normal secondary mirror is removed and, later, threaded in as complete, adjusted unit.
♦ Question: has using the Hyperstar optics any disadvantages?
Answer: yes, you will never again want to go to bed in clear, moonless nights.
The HyperStar turns your Celestron C14 SC into a fast 350 mm f/1.9 CCD telescope for astrophotography
♦ Suitable for all Celestron C14 SC telescopes (not EHD)
♦ The 350 mm f/11 SC system becomes a fast CCD astrograph with 684 mm focal length and the focal ratio f/1.9
♦ The Hyperstar system is inserted instead of the secondary mirror
♦ Focusing is still done via the primary mirror of the telescope
♦ Due to f/1.9, exposure times become so short that autoguiding is not necessary
♦ Distance to the camera sensor: 67.4 mm from the top edge of the Hyperstar (with male thread)
♦ Illuminated and corrected field - 27 mm diameter
