Baader T-Ring for Nikon

Baader T-Ring for Nikon

This Baader T-ring connects a Nikon DSLR camera body to the Astro T-2 system. The camera side uses the Nikon bayonet, while the telescope side provides an M42 × 0.75 female thread.

Mechanical dimensions

The manufacturer’s table gives an optical adapter length of 8 mm, an inner diameter of 40 mm and an outer diameter of 55 mm. Its description identifies the standard 55.0 mm reference from the front T-ring support surface to the camera’s image plane.

Camera selection

Use the ring for the stated DSLR bayonet. This is a mechanical adaptation to T-2; it does not add electronic lens communication or change the telescope’s focal length.
