This stainless steel extra long replacement counter-balance shaft is designed to fit the Sky Watcher HEQ5 and HEQ6 equatorial mounting and allow the balancing of telescopes up to 10" (or 12" with HEQ6) without the addition of excessive counterbalance weights.
The polished shaft is 46cm (18") long and replaces the existing shaft completely. The existing shaft is easily removed by simply loosening three grub screws just below the telescope mounting point.
A very useful modification for the popular Sky Watcher HEQ5 mounting.
