2" Barrel Extension w/ 48 mm Threads (EXT48-12.7)

Description This 2" x ½" Barrel Extension is a more robust version of T-thread extension tubes. It uses 48 mm threads at both ends (female and male) instead of the smaller 42 mm T-threads. Its internal light baffles are painted flat-black to avoid reflections. Use more than one to increase spacing distance and/or telecompression in 1/2" (12.7 mm) increments. This extension has a net spacing distance of 0.5" (12.7 mm). Spacer for the 0.67 CCD Telecompressor (CCDT67) to achieve precise and/or additional telecompression Moves the CCDT67 further into the optical path, requiring less focuser in-travel Use with our 1.25" Adapter (ADA125) when using 2" filters and needing more space for long barrel eyepieces, so as to not strike the filter Extends the eyepiece barrel length of 1.25"/2" eyepieces for use with 2" filters Use with the Convertible Photo-Visual Barlow (BARCON) in front of the MaxBright Diagonal (PMDMAX) for increased magnification Facilitates focus with short focuser-travel systems like Newtonians Use with parfocal rings (obtained elsewhere) to accommodate eyepiece parfocality
