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.
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.
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. Camera-family bayonets must be matched rather than selected from the camera brand alone.
Baader manufacturer documentation
Exact standard T-ring SKU matched, not UltraShort or Wide-T-ring. Optical adapter length and the manufacturer’s nominal 55 mm camera-system reference are retained as separate published statements, not recalculated from an assumed camera flange distance. Canon EF DSLR is not Canon RF; the Nikon DSLR ring is not a Nikon Z mirrorless ring.
