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.
QHYCCD QHYOAG-L has M62/0.75 telescope interface suitable for 36 x 24mm, 37 x 37mm, and 48 x 36mm sensor sizes. Direct connection to the camera with six M3 screws (62mm diameter of screw hole positions) ensures connection accuracy and parallelism. Compatible with QHY16803, QHY09000, QHYCFW-XL Includes a precision 1.25-inch helical focuser that accepts QHY5II and QHY5III guide cameras.
The Celestron Off-Axis Guider uses a prism to intercept a small portion of the telescope’s focal plane (outside the field of view of the main imaging camera) to locate a guide star.
Any movement seen by the guide star will be the exact same movement seen by the imaging camera.
Guiding this way will correct for tracking errors, as well as opto-mechanical errors or flexure. The result: better astroimages with pinpoint round stars.
The Off-Axis Guider is an essential astro-imaging accessory for long focal length telescopes that require the most accurate guiding possible.
