I ordered one of these but no longer required. It is brand new.

2" to 1.25" eyepiece adapter included.
Lock screw for eyepiece/adapter.
Threaded for 48mm Filters
Aluminium body
Internal antireflection baffling for highest contrast.
Compression rings (both on diagonal and adapter) to prevent barrels from marring.
