TS-Optics adapter from 1.25" connection to T2 and to 1.25"

TS-Optics Focal Adapter and Extension Tube

The adapter fits into 1.25" focusers and allows for prime focus photography through the telescope using a camera without a lens. In addition, the adapter features a 1.25" receptacle on the camera side. It can therefore also be used as an extension tube.

Applications

Astrophotography with refractors, Cassegrains, and Maksutovs

Direct observation with refractors (an extension tube is required because these instruments are always designed for use with star diagonals.)

Component for eyepiece projection. The adapter also holds 1.25" eyepieces. With a suitable T2 extension tube, you can take advantage of the magnifying effect, e.g., for planetary photography. When using our TS-Optics T2 extension tubes, eyepieces with a diameter of up to approximately 37 mm can be used.

What is prime focus photography:
In prime focus photography, the camera lens is removed and the camera body is attached directly to the telescope. The telescope acts as the camera lens. Since the focal length of the telescope is usually longer than that of a standard camera lens, this method allows you to capture impressive close-ups of distant objects.

What is eyepiece projection:
In eyepiece projection, an eyepiece is placed between the camera (without a lens) and the telescope. Eyepiece focal lengths between 9 mm and 15 mm are typically used. The high-magnification effect of the eyepieces can be utilized in photography. This makes it easier to photograph fine craters on the Moon or planets.
