The air-spaced doublet features an internal fluorite lens and is coated with a hard multicoating.<\/p>\n<h3>Focus and Size<\/h3>\n<p>The 50.8 mm sliding rail allows you to create a visual or photographic display using the appropriate connectors. The tube measures 785 mm with its fixed anti-fog shield.<\/p>\n<h3>Photo montage<\/h3>\n<p>The 76D-FL corrector, the FC\/FS MFL1.04X multi-flattener, and the 76D-RD and FC-35RD reducers are available as options. Takahashi specifically recommends the FC-35RD for APS-C sensors or larger. The choice of adapter rings and the distance to the sensor depends on the specific telescope and corrector selected.<\/p>\n<h3>Delivered Contents and Assembly<\/h3>\n<ul>\n<li>1 FC-100DF TFK10110 optical tube; ;<\/li>\n<li>1 cross-linked filter, 6\u00d730 <a href=\"https:\/\/deep-space-astronomy.ch\/en\/product\/takahashi-tka00551-chercheur-6x30\/\">TKA00551<\/a> ;<\/li>\n<li>1 research position (TKA00562); ;<\/li>\n<li>1 95S necklace <a href=\"https:\/\/deep-space-astronomy.ch\/en\/product\/takahashi-tka21420-collier\/\">TKA21420<\/a>.<\/li>\n<\/ul>\n<p>The researcher helps with alignment, while the collar holds the tube in place on a suitable mount.<\/p>\n<p>Choose a mount that is compatible with your equipment, and check that the assembly is balanced and securely fastened.<\/p>\n<p><a href=\"https:\/\/takahashi-europe.com\/references\/TFK10100\/fr\" target=\"_blank\" rel=\"noopener\">Takahashi FC-100DF Documentation<\/a><\/p>\n<h3>Accessories for Your System<\/h3>\n<ul>\n<li><a href=\"https:\/\/deep-space-astronomy.ch\/en\/product\/takahashi-tka00582\/\">1.04x Multi-Corrector No. 80N for FS-60CB\/FC-76\/FC-100 (TKA00582)<\/a> : optional accessory, sold separately.<\/li>\n<\/ul>\n<h3>Taking Photos with the New FCT-L Accessories<\/h3>\n<p>The <a href=\"https:\/\/deep-space-astronomy.ch\/en\/product\/reducteur-focale-takahashi-fct-l-08x\/\">Takahashi FCT-L 0.8x Focal Reducer<\/a> allows the FC-100DF to be used at 587 mm and f\/5.9, with an image circle of 44 mm.<\/p>\n<p>The <a href=\"https:\/\/deep-space-astronomy.ch\/en\/product\/correcteur-champ-takahashi-fct-l-099x\/\">Takahashi FCT-L 0.99x Field Corrector<\/a> flattens the field while maintaining a focal length of 734 mm at f\/7.3, with an image circle of 55 mm.<\/p>\n<p>These two accessories are sold separately and use the FCT-L CO 100DF ring, which is compatible with the FC-100DF.
