The EMO Wetzlar EmoScop is made of macrolon, it has one advantage over the metal Seibert-Emoskop: in telescope mode, the inner tube of EmoScop has a internal groove such that the eyepiece tube cannot be pull out without squeezing the tube, unlike the Emoskop the inner tube can be pull apart easily. <p> Hence the EmoScop telescope can be focused as close as 6". The original Seibert Emoskop close focus to about 8". <p> In Havershill website, it says that Episcope/telscope can focus close to 6", that is incorrect. Episcope/telescope's closest range is about 12"
