The Sky-Watcher & Clones to T thread Adapter for Straight Through Finders Connects ZWO, QHY6 and Orion SSAG cameras with the T Thread to Sky-Watcher, most Celestron and Orion 8 x 50 & 9 x 50 straight through finders.
Other T thread guide cameras will be compatible if their sensors are around 10mm – 15mm below the front surface of the camera.
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 contact us prior to 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
