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:
- iOptron CEM60/CEM60EC
- GEM45/GEM45EQ
- iEQ45 Pro
- iEQ45
It can be used for other mount with a 28mm diameter counterweight shaft.
