Celestron

Celestron 1mm T Thread Adapter for Right Angled Finders connects ZWO, QHY6 and Orion SSAG cameras to Celestron Finders with 1mm rear finder thread. Most Celestron finders are the same as Sky-Watcher  with 11 fine threads cut into the rear of the finder tube.

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