Eyepiece and telescope pairing
Connecting a camera to the Sky-Watcher Skymax 180
The exact thread or barrel that lets a camera reach prime focus on the Sky-Watcher Skymax 180, and the adapter that makes it work.
- Telescope interface
- Maksutov rear thread (brand-specific), with a 1.25 in visual back as the fallback
- Adapter needed
- the telescope brand's Maksutov T-adapter, plus a camera-brand T-ring
- Camera-side thread
- T-thread (M42 x 0.75), via a camera-brand T-ring
- Prime-focus focal length
- 2700 mm (f/15)
Threads on with the matching Maksutov adapter. The Sky-Watcher Skymax 180 takes a Maksutov T-adapter on its rear thread, then a T-ring for your camera, reaching prime focus at a 2700 mm focal length.
A camera reaches a telescope's prime focus through a T-adapter that matches the telescope's interface on one side and the standard T-thread, M42 x 0.75, on the other. A camera-brand T-ring then bayonets to the body.
The long 2700 mm focal length makes this a lunar and planetary imaging tube; for that work many imagers instead use eyepiece projection or a 1.25 in nosepiece camera in the focuser rather than prime-focus T-threads.
