Description
Fast-Focus Secondary Mirror Focuser for the C-11 / C1100 EdgeHD telescope.
Optec’s FastFocus Secondary Mirror Focusing System with FocusLynx Controller has proven itself to be a singularly unique solution to the limited back-focus of the Celestron EdgeHD telescopes. With the FastFocus system in place, any Fastar compatible Celestron OTA can function like many professional telescopes where only the secondary mirror moves to adjust the focus. The primary mirror and entire imaging train can be locked in place avoiding flexure and tilt at the image plane.
This requires the FocusLynx Controller Hub in order to function.
