This newly designed 5kg (11lb) counterweight (CW) uses compression ring to lock the CW onto a CW shaft. Comparing to traditional "point contact" locking mechanism via a locking screw and a pin, the compression ring provides more secure locking method through distributed surface contact.
This CW is designed for following iOptron Mount:
CEM70/CEM70EC/CEM70G
CEM60/CEM60EC
GEM45/GEM45EC/GEM45G
CEM40/CEM40EC/CEM40G* (for late version with 28mm CW shaft)
iEQ45 Pro
iEQ45
It can be used for other mount with a 28mm diameter counterweight shaft.
The Crayford GSO eyepiece lift with linear bearings is a modern, technically advanced spectacle lift, which is a breakthrough among this type of device. The structure was designed based on two precision bearings moving on a steel rail, which improves the precision of adjustment and ensures increased load capacity (4.1 kg) compared to standard lifts. This allows stable attachment of even heavy astrophotography accessories.
