Baader Planetarium Expanding Ring T-2/M48

• Baader's T-2 / M48 Expanding Ring converts internal 2" Filter threads to internal T threads
• Baaders T-2 / M48 has external M48 threads on one side and internal T-threads on the other
• Baader's Expanding Ring is useful in adapting accessories that are threaded to accept standard 2" Filters

Baader's growing line of threaded couplers enable enthusiasts to convert T-2 threaded parts for alternative thread sizes or genders. These convertors allow users to firmly couple to various manufacturer's telescope focuser threads or to combine T-2 parts into useful configurations. The fully sharp V-threaded and blackened internal surfaces cancel any stray light reflections and the precision threading guarantees a proper fit.
