Imagine a mount head weighing in at just 8.15 lb. but with a payload capability 29.74 lb., and without the need for a cumbersome counterweight or counterweight shaft!\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eUtilizing state of the art harmonic drive technology for the RA movement in tandem with backlash-free DEC worm\/belt drive design, the iOptron HEM27EC delivers unparalleled weight to payload efficiency. Its black anodized all-metal CNC machined body is not only appealing to the eye, it’s a rugged platform that will perform at the highest level for many years to come. Unique features such as an electronic friction break and power down memory allow the mount to safely stop and resume a GoTo slew or continue tracking even after an abrupt power loss (no need to realign and start from the beginning). \u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe HEM27EC package\u003c\/span\u003e\u003cspan\u003e features a high precision RA axis encoder that delivers incredible tracking accuracy, enough that many will choose to image “sans” guiding and comes with iPolar, an electronic polar scope for easy and accurate polar alignment.  Other optional HEM27 models include the base version (H272) or the base version with iPolar (H272A).  Only the HEM27EC (H274A) comes with the high precision RA encoder.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cmeta charset=\"UTF-8\"\u003e \u003cb\u003eFeatures\u003c\/b\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAdvanced harmonic drive technology\u003c\/li\u003e\n\u003cli\u003ePayload capacity of 13.5 kg (29.7 lbs) with the mount weight of 3.7 kg (8.15 lbs)\u003c\/li\u003e\n\u003cli\u003eCNC machined and cast metal body\u003c\/li\u003e\n\u003cli\u003eUnique friction brake to safely stop movement during a planned or unplanned power interruption\u003c\/li\u003e\n\u003cli\u003e360 second gear period\u003c\/li\u003e\n\u003cli\u003eHigh precision encoder with realtime PEC (RPEC)\u003c\/li\u003e\n\u003cli\u003eGo2Nova® hand controller with ~212,000 object database\u003c\/li\u003e\n\u003cli\u003eiPolar electronic polar scope for easy and accurate polar alignment\u003c\/li\u003e\n\u003cli\u003eCable management system, no hanging exterior cables to moving parts\u003c\/li\u003e\n\u003cli\u003eDual saddle (vixen and losmandy-D styles)\u003c\/li\u003e\n\u003cli\u003eBuilt in zero position search and locator\u003c\/li\u003e\n\u003cli\u003ePower down position and location memory\u003c\/li\u003e\n\u003cli\u003eIntegrated ST-4 autoguiding port\u003c\/li\u003e\n\u003cli\u003eBuilt-in Wi-Fi (via hand controller)\u003c\/li\u003e\n\u003cli\u003eUSB port for firmware upgrade and computer control\u003c\/li\u003e\n\u003cli\u003eSoft carrying case\u003c\/li\u003e\n\u003cli\u003eTwo year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable cellpadding=\"0\" cellspacing=\"0\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd align=\"right\" width=\"217\"\u003eMount\u003c\/td\u003e\n\u003ctd align=\"center\" width=\"354\"\u003eHybrid Equatorial Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd align=\"right\" width=\"217\"\u003eRA Gear system\u003c\/td\u003e\n\u003ctd align=\"center\" width=\"354\"\u003eStrainWave 17 (RA)\/worm gear (DEC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd align=\"right\" width=\"217\"\u003eDEC Gear system\u003c\/td\u003e\n\u003ctd align=\"center\" width=\"354\"\u003eBacklash-free worm\/belt system\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd align=\"right\" width=\"217\"\u003eRA reduction ratio\u003c\/td\u003e\n\u003ctd align=\"center\" width=\"354\"\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd align=\"right\" width=\"217\"\u003ePayload w\/o CW \u003c\/td\u003e\n\u003ctd align=\"center\" width=\"354\"\u003e29.14 lbs (13.5kg) - \u003cspan data-mce-fragment=\"1\"\u003e200mm, with payload center of gravity to the RA rotation axis.
