Hyper Star C11 - photographical system for the Schmidt-Cassegrain f/2 prime focus

  • Turn your Celeston SC into a Schmidt camera

Celestron USA was one of the first big telescope manufacturers who was able to design fast Schmidt cameras for the consumer market. With the Hyper Star system, Celestron tied in with this tradition. In a few minutes, you can turn your Schmidt-cassegrain into a fast f/2 Schmidt camera suitable for the high resolution of modern CCD sensors.

The Hyper Star system replaces the secondary mirror:

By easy adapting the Hyper Star system to the Schmidt plate, you can change within a few minutes between the f/2 and the f/10 focus of your SC telescope.

Your SC telescope must be Fastar compatible - this is how it's prepared:
If your SC is already Fastar compatible, you just need to install the Hyper Star kit. For all other SCs, we offer the Hyper Star kit and (if you want) the alteration, too.

What is the Hyper Star system and how does it work?

Hyper Star is a multi-lens corrector system which replaces the secondary mirror and corrects for the remaining abbreviations of the main mirror. Coma and field curvature are completely eliminated so you have a wide and flat field for photography. Simply spoken, you get an easy-to-use Schmidt Camera for the digital era.
