Description
The 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
