Takashi Wide T-Rings (M54 threaded) for Canon EOS, Nikon, Pentax K, Minolta-AF and Sony Alpha 7 (E)
The so-called "T-ring" is an indispensable accessory for anyone who wants to attach a digital camera to the optical tube of a telescope. Specific to the brand of camera, it ensures the connection between the camera body and the photo adapter of the instrument. Each ring has a specific length that ensures a fixed distance of 56.2 mm between the camera sensor and the bearing surface of the instrument's photo adapter.
Takahashi Wide T-rings have a larger M54x0.75 threaded inlet diameter than the standard T-rings (M42x0.75). This larger diameter makes it possible to use full-frame cameras without vignetting, whereas the standard T-ring only just covers the APS-C format. However, it should be remembered that for these cameras to be fully usable, it is imperative that either the instrument itself or its corrector or reducer has a minimum corrected image circle of 43.3 mm in diameter, which is necessary to cover the 24x36 format. Please refer to the system-charts of each instrument for the choice of the T-ring according to the desired mounting.
Takahashi Wide T-rings are composed of 2 elements: a central ring with a male M54x0.75 thread on the input side and a brand specific camera bayonet on the output side. If necessary, it is possible to remove the central ring and replace it by a model offering either a female M42x0.75 thread (the ring becomes a "Standard T-ring"), or a female M52x0.75 thread (the ring becomes a "Wide FS-60 T-ring" intended for the Takahashi FS-60 refractor).
The T-Rings will bring the cameras out to 55mm backfocus, which is why the Sony model has a longer built-in extension.
