The updated model is faster and offers greater versatility in the same compact, yet solid, focuser design.\u003cbr\u003e\u003cbr\u003eThe TCF-LSI has all of the control electronics integrated into the focuser body. This means that you do not need any external controller. Simply connect power and the control cable and you are ready to begin. The TCF-LSI uses the same drivers as the rest of our FocusLynx family of focusers.\u003cbr\u003e\u003cbr\u003eAs a robust Crayford style 2-inch focuser, the TCF-LSI drawtube accepts any of our 2-inch adapters developed especially for the TCF-S and TCF-Lynx focusers. The optional 1-1\/4\" Centering Adapter allows any 1-1\/4-inch diagonal or eyepiece to be added behind the focuser. Visual users will appreciate the In-Out Keypad for no-touch operation of the telescope focus.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003cbr\u003e\n\u003c\/h3\u003e\n\u003ctable style=\"box-sizing: border-box; margin: 0px; width: 1129.13px; border-collapse: collapse; color: #000000; font-family: 'Open Sans'; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e\n\u003ctbody style=\"box-sizing: border-box; margin: 0px;\"\u003e\n\u003ctr style=\"box-sizing: border-box; margin: 0px;\"\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 566.515px;\"\u003eOverall Height:\u003c\/td\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 561.676px;\"\u003e3.3\" (84mm) to 3.9\" (99mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"box-sizing: border-box; margin: 0px;\"\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 566.515px;\"\u003eFocuser Travel:\u003c\/td\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 561.676px;\"\u003e0.6\" (15.2mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"box-sizing: border-box; margin: 0px;\"\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 566.515px;\"\u003eFocuser Midpoint\u003c\/td\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 561.676px;\"\u003e3.6\" (91.4mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"box-sizing: border-box; margin: 0px;\"\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 566.515px;\"\u003eTotal Step Travel:  \u003c\/td\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 561.676px;\"\u003e7,000 steps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"box-sizing: border-box; margin: 0px;\"\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 566.515px;\"\u003eStep Resolution: \u003c\/td\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 561.676px;\"\u003e2.2 microns\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"box-sizing: border-box; margin: 0px;\"\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 566.515px;\"\u003eWeight: \u003c\/td\u003e\n\u003ctd style=\"box-sizing: border-box; margin: 0px; padding: 10px; border: 1px solid #eeeeee; text-align: left; width: 561.676px;\"\u003e2lb. 4oz.
