Vai al moduloCelestron Universal T-Adapter 1.25" for DSLR and mirrorless cameras
The Celestron Universal T-Adapter 1.25" (item 93625) is a photographic adapter that connects a DSLR or mirrorless camera, without its lens, to any telescope, spotting scope or accessory fitted with a 31.8 mm (1.25") focuser for prime focus photography. The chrome barrel slides into the focuser like an ordinary eyepiece, while the T2 thread (M42x0.75 mm) on the opposite end accepts the T-ring made for your camera mount, sold separately.
How to mount it
- Screw the T-ring matching your camera system (Canon, Nikon, Sony, Micro 4/3 and others) onto the T2 thread of the adapter.
- Attach the camera, without its lens, to the T-ring.
- Slide the 1.25" barrel into the telescope focuser and tighten the thumbscrew.
- Focus with the telescope focuser, using live view to help.
What it is used for
- Moon shots and short-exposure planetary and solar imaging (with a suitable filter)
- Terrestrial photography with spotting scopes and telescopes: landscapes, wildlife and distant details
- Use with a 1.25" Barlow lens, by inserting the adapter into its socket to increase magnification
Main features
- Telescope side: 31.8 mm (1.25") chrome barrel
- Camera side: T2 thread (M42x0.75 mm)
- Material: anodized aluminum and chrome plating
- Prime focus use, with the camera body mounted without a lens
- Camera-specific T2 ring: not included
Compatibility and requirements
The adapter fits any instrument that accepts 1.25" accessories: refractors, reflectors, catadioptrics, spotting scopes, diagonals and eyepiece holders. Prime focus requires about 40 mm of backfocus: some telescopes, especially fast refractors and most Newtonians, may not have enough focuser travel to reach focus. In these cases Celestron recommends the Universal Barlow and T-Adapter 93640, which doubles the magnification and lets the telescope reach focus. Vignetting at the image edges may appear with full-frame cameras.
Frequently asked questions
Does the Celestron T-Adapter 93625 work with mirrorless cameras?
Yes, as long as you use the correct T2 ring for your mirrorless camera mount. The ring is not included in the package.
Do I need to remove the camera lens?
Yes. In prime focus the telescope acts as the telephoto lens, so the camera must be used without its lens.
Why can't I reach focus?
The telescope focuser may not have enough inward travel. Check the available backfocus before buying (about 40 mm is needed) or consider using a Barlow lens.
Is it suitable for a heavy camera?
The camera is carried by the focuser and held by a thumbscrew: check that it is tight and rebalance the telescope after mounting.
