The “center balance” design’s natural stability is due to its focusing the mount along with any payload's weight directly over the center of the pier or tripod. The CEM120EC performance is demonstrated by its low periodic tracking error of  \u0026lt; 0.15 arcsecond RMS for this EC model.\u003c\/p\u003e\n\u003cp\u003eAlong with stability, the CEM120EC Center Balanced Equatorial Mount features an advanced cable management system consisting of more ports in more locations, preventing cable tangles and reducing the chance of fractured cables. It also adds some new features to the CEM family like Wi-Fi and LAN for remote operation and easy to use, reliable clutches on both axes. This product is the CEM120EC High-Resolution mount, with a Hi-Res. Encoder on the Right Ascension (RA) axis (but not on the Dec axis).\u003c\/p\u003e\n\u003cp\u003eThis product's number is IOP-7301.\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eiOptron CEM120EC Center Balanced Equatorial Mount Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eA new design, center-balanced equatorial mount (CEM) for maximum payload with natural stability and advanced operating specs\u003c\/li\u003e\n\u003cli\u003eObservatory astrophotography mount ideal for both visual observation and astrophotography applications\u003c\/li\u003e\n\u003cli\u003ePayload of 115 lb (52 kg) with the mount weight of 57 lb (26 kg)\u003c\/li\u003e\n\u003cli\u003eEasy to use and reliable gear clutches\u003c\/li\u003e\n\u003cli\u003eAdjustable counterweight shaft for 0º latitude operation\u003c\/li\u003e\n\u003cli\u003ePrecision altitude and azimuth adjustment\u003c\/li\u003e\n\u003cli\u003ePrecision stepper motor with 0.07 arcsec accuracy for precise GOTO and accurate tracking\u003c\/li\u003e\n\u003cli\u003ePolar alignment routine for those who can't see the Pole Star\u003c\/li\u003e\n\u003cli\u003eGo2Nova® 8407+ controller with Advanced GOTONOVA® GOTO Technology with built in heater\u003c\/li\u003e\n\u003cli\u003eHigh-Resolution Encoder on the RA Axis (only)\u003c\/li\u003e\n\u003cli\u003eReal time PEC (RPEC) for the CEM120EC High Resolution model\u003c\/li\u003e\n\u003cli\u003eBuilt-in 32-channel Global Positioning System (GPS)\u003c\/li\u003e\n\u003cli\u003eBuilt-in Wi-Fi and LAN for remote operation\u003c\/li\u003e\n\u003cli\u003eIntegrated ST-4 auto guiding port\u003c\/li\u003e\n\u003cli\u003eAdvanced cable management system with more choices\u003c\/li\u003e\n\u003cli\u003eMount includes 2 counterweights (10 kg each)\u003c\/li\u003e\n\u003cli\u003eSpring loaded, individually-adjustable Losmandy-style Saddle\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: center;\"\u003eSpecifications:\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel:\u003c\/td\u003e\n\u003ctd\u003eCEM120EC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMount Type:\u003c\/td\u003e\n\u003ctd\u003eCEM (Center balanced EQ Mount)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePayload (excluding CW):\u003c\/td\u003e\n\u003ctd\u003e52 kg（115 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMount Weight:\u003c\/td\u003e\n\u003ctd\u003e26 kg (57 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePayload per Mount Weight:\u003c\/td\u003e\n\u003ctd\u003e2X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLatitude Adjustment Range:\u003c\/td\u003e\n\u003ctd\u003e0～68° (0.5 arc min divisions)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAzimuth Adjustment Range:\u003c\/td\u003e\n\u003ctd\u003e±5° (3 arc min division)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTracking Accuracy (PE):\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;
