TS-Optics Collimation Screws for Celestron SC and EHD Telescopes
An SC or EHD telescope must always be perfectly collimated to provide the best possible image. A regular check of the collimation at the star is necessary. However, it is not everyone´s cup of tea to handle a hexagon socket wrench in front of the sensitive Schmidt plate in the dark. The TS-Optics knurled screws offer a remedy.

The knurled screws offer a generously grooved upper side for very precise adjustment without tools. A big advantage for example compared to the Bob´s Knobs screws are the different surfaces, which allows you to distinguish the screws even in the dark and thus always turn the right screw. Each screw has a rubberized and rounded surface, one with a CNC engraved notch and one with a flat head.

The collimation screws fit almost all Celestron SC and EHD telescopes from 5" to 14" aperture. The matching spacers are included and the instructions tell you which spacers are needed for which telescope.
C5: 2 spacers per screw
C6: no spacer
C8 without Fastar: 2 spacers per screw
C8 with Fastar: 1 spacer per screw
C8 Edge HD with/without Fastar: no spacer
C9.25 without Fastar: 1 spacer per screw
C9.25 Edge HD without Fastar: 1 spacer per screw
C11 without Fastar: no spacer
C11 Edge HD without Fastar: no spacer
currently there is no compatibility with EHD925, C9.25, EHD1100, C11 with Fastar.


Important: Some Celestron SCTs have American threads for adjusting the secondary mirror. The knobs are not suitable for these inch threads. Types of standard collimation screws for matching threads:

C5: black Phillips screws
C6: have metric collimating screws only
C8: black Phillips screws
C9.25: black Phillips screws and more text than serial number sticker nearby
C11: Black Phillips and "279mm" screws nearby
Suitable for telescopes:Celestron SCT and EHD
Thread type:Metric
Material:Aluminium with anti-scratch coating
Set of 3 collimation screws

"Ich verwende die Rändelschrauben an einem c6. Installation ist sehr einfach. Erleichtert die Kollimation extrem. Der Deckel passt auch noch drauf. Wahrscheinlich das beste Zubehör überhaupt."

"Conforme à la description, mais ce n´étaient pas les bons pour mon SC. Les vrais Bob´s Knobs sont plus design. "
