iOptron Electric Focuser for Ritchey-Chrétien OTA Dual-Speed Focuser # 8451

This focuser is normally intended for Ritchey-Chrétien reflectors, but also works fine in conjunction with TS-Optics T90/600 refractor (after a slight modification of the pulley: I just had to enlarge the central bore of the pulley by around 0.5mm so that it now fits on the tuning shaft of the TS.Optics scope as well. 

Features:

 Whisper quiet operation

 Powerful stepper motor

 Zero backlash

 Plug into iOptron Port with no external power source needed

 3 speed control by a compatible iOptron hand controller

Currently supported mount (with firmware version V161101 or later):

 CEM25/CEM25P/CEM25EC

 CEM40/CEM40EC

 CEM60/CEM60EC

 iEQ30 Pro

 iEQ45 Pro

Warning: please use iOptron Commander version V5.8 or later, I experienced some compatibility problems with older Commander version and warning messages like “outdated firmware” resulting in unstable operation. Since I updated the iOptron Commander software to V5.8 on Feb. 24, 2021, I no longer received such warnings.
