Eyepiece and telescope pairing
Connecting a camera to the Celestron NexStar 6SE
The exact thread or barrel that lets a camera reach prime focus on the Celestron NexStar 6SE, and the adapter that makes it work.
- Telescope interface
- 2 in x 24 TPI SCT rear-cell thread
- Adapter needed
- Celestron T-adapter for Schmidt-Cassegrain telescopes, plus a T-ring for your camera brand
- Camera-side thread
- T-thread (M42 x 0.75), via a camera-brand T-ring
- Prime-focus focal length
- 1500 mm (f/10)
Threads on directly. The Celestron NexStar 6SE has the standard 2 in x 24 TPI SCT rear-cell thread, so a Celestron SCT T-adapter screws straight on and a camera-brand T-ring then mounts the body at prime focus, giving a 1500 mm native 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.
At prime focus the whole telescope acts as a 1500 mm f/10 lens. A focal reducer that also threads to the SCT rear cell shortens this for a wider field and faster exposures.
