About
A robust half-inch extension tube that uses 48 mm threads at both ends — female and male — rather than the narrower 42 mm T-thread, with flat-black internal baffles against reflections. Stack several to add spacing or telecompression in half-inch steps; threaded onto eyepiece barrels the same part serves as a barrel extension.
