Used Starizona Hyperstar v4 for Celestron 11" EdgeHD

Condition: This is a used Starizona Hyperstar for a 11" Celestron EdgeHD.  This is the latest version, version 4, as shown on the body.  It is in excellent condition, with absolutely clean, pristine optics and an unmarked body.  

NOTE: Different camera models will require different adapters, so the HyperStar maker, Starizona, makes user-interchangeable camera adapters for their V3 and V4 Hyperstars. (**You’ll also need a counterweight system if you’re using a fork mount.)

You’ll find them at Starizona.com—search for “HyperStar Camera Adapter.” Since it’s important to get the exact match between camera and telescope (camera make and model, telescope aperture, Edge HD or not, etc.), it’s probably best to give Starizona a call to ensure you get exactly the right adapter: 520-292-5010.

Starizona HyperStar 4 for Celestron 11” Edge HD

Take images 25 times faster by adding the Starizona HyperStar 4 multi-lens corrector and reducer to the front of your Celestron 11” EdgeHD’s optical system! The HyperStar replaces the secondary mirror on the Celestron 11" SCT OTA. Removing the secondary takes only a few minutes with no tools required. There is even a holder for the secondary included to keep the optics safe when not in use. Once the secondary has been removed, simply mount the HyperStar in its place, add your choice of camera (APS-format or smaller), and start imaging at f/1.9. You will experience a much wider field of view as well as lightning speed exposures. When it comes time to replace your secondary, no collimation is required. The secondary lens is indexed so you will know its proper orientation.

It is amazing how fast your exposure times will be once you’ve added HyperStar to the mix! For example, an exposure that takes 25 minutes at f/10, or 10 minutes at f/6.3, will take less than 60 seconds at f/1.9! Saving time is not the only benefit of imaging with HyperStar, however. The greatest advantage of consistently fast exposure times has to do with guiding, or should I say, the lack of guiding! The longer an exposure becomes, the more likely it will suffer from tracking errors, accidental bumps to the telescope, and other problems that cause out of focus images or star trails. However, with typical exposure times of 20 - 60 seconds, guiding is usually unnecessary.
