We are pleased to introduce the new EVOSTAR-100EDX model, which is the result of several very useful mechanical improvements, and a change in its focal ratio from f\/9 to a much faster and more imaging-friendly f\/7. Presented in its stunning new white and green livery, the EVOSTAR-100EDX is a superb instrument for both imaging and visual use, with the necessary accessories.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe new EVOSTAR-100EDX model includes an enlarged 2.8” indexed focuser drawtube with a built-in 360° rotatable adaptor, a retractable dew shield and a convenient carrying handle.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eNow featuring f\/7 matched optics including one premium Japanese Ohara FPL-53 ED glass lens element which virtually eliminates chromatic aberration.
