These light weight, high payload tiny titans will deliver an astronomy experience like never before. Imagine a mount head weighing in at 8.15lbs with a payload capability 29.74lbs, without needing a cumbersome counterweight or shaft. Applying iOptron’s multi decade experience creating precision mounts, the HEM27 brings this vision to reality.\u003cbr\u003e\u003cbr\u003eUtilizing state of the art strain wave drive technology for the RA movement in tandem with backlash-free DEC worm\/belt drive design, the HEM27s deliver 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 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).\u003cbr\u003e\u003cbr\u003eA HEM27 mount can be controlled by a computer, either via ASCOM\/Commander for a Windows PC or a third party INDI driver for a MacOS software; a SmartPhone\/Tablet via iOptron Commander Lite or an App like SkySafari; or a Raspberry Pi device via INDI driver.\u003cbr\u003e\u003cbr\u003eThe HEM27EC features a high precision RA axis encoder that delivers incredible tracking accuracy, enough that many will choose to image “sans” guiding.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAdvanced strain wave 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\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\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"font-size: 13px;
