T2SCT Setup Diagram

Why not just use a T-Ring?

Simply put todays equipment has outgrown the T-Ring. The "T2" T-Ring standard was developed by Tamron in 1957. It's purpose was to specify a common focus point when connecting 35mm Film Cameras to aftermarket camera lenses. In the 1950s the standard telescope port size was .96" and the Nikon F Mount was 40mm. Now telescope Port Size is 2" and the Nikon Z mount is over 49mm! The Clear Aperture of a T-Adapter is about 1.5" (38mm). Depending on your setup you can expect at least some vignetting when using a T-Ring setup.

What is Vignetting?

Vignetting is simply shading of the camera sensor. Since the light rays in a telescope are not parallel a restriction in the clear aperture can have more serious consequences than expected. Even if the restriction is larger than the sensor it can be at a place where the light rays will still be clipped by the angle. The shorter the Focal Ratio of the scope the steeper this angle and the worse it can be. The shaded area of the sensor will be dark and essentially wasted. The result in your images will vary depending on the degree of vignetting. Minor vignetting may clip the corners off the image, whereas more significant vignetting will give you a circular image in a dark field. Sure you could do extra work to enlarge and crop your images in a pc. But that can mean accepting a lot of loss in both image quality and overall value. Especially if you have an expensive camera. After all, what did 15% of that sensor cost?
