With precise GOTO pointing and accurate tracking, the iOptron CEM70EC is suitable for observers and imagers alike. It offers advanced operational features such as the internal iPolar electronic polar scope, easy lock drive gear engagement (with levers large enough to use with gloves), cable management, and much more.
Note:
The included AC adapter is for indoor use only.
