Designed for CR150, Sky-Watcher and other 150mm refactor OTA's.
Sleeve design fits and adjusts snuggly on the OTA with rubber tipped non-marring nylon set-screws. Stainless-steel counter-weight is fully adjustable with carrying handles. This system raises the tube 12"-15" higher on the mount for improved eye-piece placement and balance. Works wonderfully. I sold my OTA, so this unit is redundant for me. God bless the Columbia 7 and their families...
