<p>&nbsp;Takahashi has just introduced an updated version of the original FC-100 now called the FC-100D. It has been designed for the digital age. The FC-100D uses the Steinheil design with the fluorite element in the rear and an eco-glass front element. The focal ratio has been reduced to f/7.4 with a 740mm fl.</p> <p>&nbsp;&nbsp;</p> <div>The FC-100D was designed with a goal of being light weight and highly portable. It is offered in two light weight models: the ultra-portable DC visual model that weighs just 2.8kg [6.1lbs] uses the 2.2&rdquo; FS-60CB focuser. While the DF model uses the 2.7&rdquo; focuser and is designed to be used for imaging as well as visual using the dedicated four element FC-35 .66x new reducer that changes the focal ratio to f/4.9 with a &Oslash; 44mm circle at a focal length of 485mm.</div> <div>&nbsp;</div> <div><span style="color: #000000; font-size: 10pt; font-family: Raleway, sans-serif; background-color: #ffffff;">The FC-100DF is optically identical to the DC model, but features an enhanced 2.7 &ndash;inch focuser.&nbsp; It also features a shorter tube length that provides additional back focus for digital imaging applications.&nbsp; This added back focus allows use of the FC-35RD reducer, which converts the DF to an f/5.4 instrument.</span><br />&nbsp;&nbsp;</div> <div><strong><span style="color: #243638; font-size: 10pt; font-family: Raleway, sans-serif; background-color: #fafafa;">Optical Tube Assembly only (mount, tripod, tube holder and finder sold separately).&nbsp;&nbsp;</span></strong></div> <div>&nbsp;</div> <div><span style="font-size: large;"><strong>FC-100DC/DF<br />&nbsp;&nbsp;</strong></span></div> <div>&nbsp;</div> <div><strong>Specifications<br />&nbsp;&nbsp;</strong></div> <div>&nbsp;</div> <div> <div class="productdata-tablelist page specs clearfix" style="color: #243638; font-size: 16px; font-family: Raleway, sans-serif;"> <ul class="specslist" style="font-size: 0.875em;"> <li class="specslist_item"><label style="color: #949494; font-size: 16px;">Aperture:</label>100 mm</li> <li class="specslist_item"><label style="color: #949494; font-size: 16px;">Focal Length:</label>740 mm, 486 mm with FC-35 Reducer, 1185 mm with Extender-Q 1.6X</li> <li class="specslist_item"><label style="color: #949494; font-size: 16px;">Focal Ratio:</label>f/7.4, f/4.9 with FC-35 Reducer, f/11.9 with Extender-Q 1.6X</li> <li class="specslist_item"><label style="color: #949494; font-size: 16px;">Image Circle:</label>44 mm with FC-35 reducer</li> <li class="specslist_item"><label style="color: #949494; font-size: 16px;">Image Field:</label>-</li> <li class="specslist_item"><label style="color: #949494; font-size: 16px;">Back Focus:</label>161 mm, 78.1 mm with FC-35 Reducer</li> <li class="specslist_item"><label style="color: #949494; font-size: 16px;">Tube Length:</label>815 mm</li> <li class="specslist_item"><label style="color: #949494; font-size: 16px;">Tube Diameter:</label>95 mm</li> <li class="specslist_item"><label style="color: #949494; font-size: 16px;">Tube Weight:</label>3.6 kg</li> </ul> </div> <div class="productdata-tablelist specs-properties clearfix" style="color: #243638; font-size: 16px; font-family: Raleway, sans-serif;"> <ul style="font-size: 0.875em;"> <li class="productdata code"><span style="color: #949494;">Code</span>&nbsp;TFK10110</li> <li class="productdata sku"><span style="color: #949494;">SKU</span>&nbsp;TFK10110</li> <li class="productdata weight"><span style="color: #949494;">Weight</span>&nbsp;20411</li> <li class="productdata sizex"><span style="color: #949494;">Size X</span>&nbsp;106</li> <li class="productdata sizey"><span style="color: #949494;">Size Y</span>&nbsp;30</li> <li class="productdata sizez"><span style="color: #949494;">Size Z</span>&nbsp;38</li> </ul> </div> </div> <div>&nbsp;</div>
