M48 to 2″ EP Adapter, a 2″ Visual Back with M48 female thread, allowing the use of 2″ eyepieces on telescopes or accessories with a male M48 thread.
Please note this adapter is supplied with one set screw at the present time.
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.
