Celestron 1mm C Mount Adapter for Right Angled Finders

Celestron 1mm C Mount Adapter for Right Angled Finders


Connects ZWO, QHY6 and Orion SSAG cameras to Celestron Finders with 1mm rear finder thread


Connects QHY5-II, QHY5L-II, Lodestar, Orion SSAIO, Mintron, Watec & DMK cameras, via the C mount adapter to Celestron Finders with 1mm rear finder thread

Most Celestron finders are the same as Sky-Watcher, and have 11 fine threads cut into the rear of the finder tube.

However some are different and we now have a separate adapter for those Celestron finders with 8 coarser (1mm) rear finder threads. Simply remove the eyepiece and holder to check.


Please ask before purchase if you are unsure 🙂


Tests have confirmed that guiding is successful at focal lengths of up to 1500mm and more.

Stability is excellent if screws are tightened firmly and cables tied up.

Using the finder as a guide-scope reduces the weight and complexity of your imaging set-up and the wide field of view guarantees finding suitable guide stars.

Adapters are near parfocal with visual focus of the finder.
