Baader 48mm/T2 Expanding Adapter Ring
This moderately sized, tough, well built expanding ring is an adapter; it converts internal M48 (2" Filter) threads to internal T-threads. The external M48 threads are on one side, and the Internal T-Threads on the other side; This ring is particularly handy in adapting accessories, like the MPCC, to the bottom of eyepieces or other accessories that are threaded to accept standard 2" Filters. The knurled exterior is well optimized for tightening it by hand, and the black anodized aluminum exterior is both sleek and durable.
