The 2" Eyepiece Barrel Extender (EBX-2120) increases backfocus distance and provides a mounting location for 2" (48mm) eyepiece filters. It can also help parfocalize eyepiece sets. Extender adds 1.2-inches to the 2" barrel.
When joining eyepieces with dual 2" / 1¼" barrels to the 2" Barrel Extender (12mm Nagler Type-4 shown), remove the lock screw in the 2" barrel section of the eyepiece.
