Alpine Astronomical Baader M36.4 /T-2 Adapter Ring

This adapter ring is part of the T-2 Astro modular system. It features standard Vixen M36.4 threads on one side and T-threads on the other. It allows direct attachment of cameras, imagers, or astrophotography accessories to Vixen optical tube assemblies. The ring is compatible with OTAs that have the same thread size. It can be used with a camera-specific T-ring for direct connection or as part of a custom system with other components like extension rings and filter holders.
