Vai al moduloArtesky Twist Lock 50.8mm Eyepiece Holder for Newton Sky-Watcher
The Artesky Twist Lock 50.8mm Eyepiece Holder is a high-precision accessory designed for Sky-Watcher Newton telescopes. It screws directly onto the original focuser thread of Sky-Watcher Newtonian models (150PDS, 200PDS, 250PDS, 300PDS, QUATTRO 8S, QUATTRO 10S, QUATTRO 12S and similar), allowing the use of any 50.8mm (2") accessories.
Unlike standard 2" eyepiece holders with side screws, the Twist Lock system provides uniform clamping pressure and eliminates flexure, ensuring perfect optical alignment. It’s an essential component for users seeking maximum stability and precision, especially in advanced astrophotography setups.
Tested Compatibility with Coma Correctors
- Sky-Watcher Coma Corrector F/5
- Sky-Watcher Coma Corrector F/4
- Baader MPCC Mark III
- Artesky Coma Corrector 0.95x
- Sharpstar MPCC 1x
- TS / Tecnosky / Omegon Coma Correctors
The self-centering Twist Lock system prevents marks or scratches on accessories while maintaining perfect optical alignment — ideal for laser or OCAL collimation. The external locking ring features an anti-slip grip design, allowing for secure tightening even in humid or cold observing conditions.
Use with CCD, CMOS or DSLR Cameras
The Artesky Twist Lock is engineered to support heavy imaging accessories such as CCD, CMOS and DSLR cameras without flexure, ensuring perfect focus alignment for astrophotography.
Usage is simple: attach a T2–50.8mm adapter to your camera and insert it into the Twist Lock. By rotating the ring toward “CLOSE,” the holder clamps the barrel evenly and securely. A 2" filter (such as a light pollution or polarizing filter) can also be threaded onto the adapter without interfering with the locking mechanism.
