The FC-100DZ is fully compatible with the accessories available used with the existing FC-100 telescopes, including the FC\/FS Muli-flattener and the FC-35 0.66X Reducer.  With FC-35 reducer, this telescope becomes an excellent imaging system, illuminating a full frame chip at f\/5.3. Mechanically, the FC-100DZ has a tube diameter of 95 mm and a retractable dew shield.  With the dew shield retracted and accessories removed, the total length is only 595 mm, easily carried on most commercial flights.  The FC-100DZ utilizes the same focuser used on the FC-100DF and DL and weighs approximately 3.8 kg.\u003c\/p\u003e\n\u003cp\u003eThe FC-100DZ is fully compatible with the accessories available used with the existing FC-100 telescopes, including the FC\/FS Muli-flattener and the FC-35 0.66X Reducer.
