Starizona HyperStar v4 for Celestron 11" SCT OTAs
The Starizona HyperStar 11 v4 transforms a compatible Celestron 11-inch Schmidt-Cassegrain telescope into an ultra-fast f/1.9 powerhouse, reducing the focal length from 2800mm to 540mm. This dramatically increases imaging speed up to 25x faster than the native f/10 system. Reducing the focal length and ratio allows you to capture deep-sky objects with shorter exposures, while also achieving a much wider field of view. The HyperStar system replaces the telescope's secondary mirror and includes a camera adapter and secondary mirror holder for a simple, complete imaging solution.

Frequently Asked Questions
Do I need the Filter Slider to use filters with the HyperStar?
No. The Standard Camera Adapter that ships with every HyperStar has an M42 threaded top that accepts one 2" mounted filter — ideal for a broadband, dual-band or IR-cut filter with a one-shot color camera. The Filter Slider is a helpful upgrade for monochrome shooters or anyone wanting to change filters throughout your imaging session.
What cameras does the included adapter work with?
The Standard Camera Adapter is M42-threaded and pre-set for 17.5 mm backfocus — which covers most popular cooled astrocameras. If your camera needs a different thread size or backfocus, check out our HyperStar Adapter page.
Are HyperStars hard to focus?
Not really. A Bahtinov mask, an autofocuser like the EAF, or any software showing FWHM all work well. The fast f/ratio does make backfocus more critical — which is why our adapters are machined with precise accuracy.
What telescopes are compatible?
Any factory Fastar-compatible C11 SCT. Older non-Fastar scopes can be upgraded with our C11 Conversion Kit. The HyperStar 11 works on both standard C11 and EdgeHD 11 OTAs thanks to the included EdgeHD Adapter Ring.
Will I need spacers for correct backfocus?
No. Every HyperStar ships with the correct adapter already set to the right backfocus. Install the HyperStar, attach your camera, and start imaging.
If I have a Non-EdgeHD HyperStar can I use the EdgeHD Adapter Ring?
Yes — non-HD v3 and v4 HyperStars can use the EdgeHD Adapter Ring to mount on the same-size EdgeHD OTA. The HyperStar 9.25 is unique and works on both standard and EdgeHD 9.25 tubes without any additional adapter.
