Its five-element, five-group lens design includes two fluorite elements to correct chromatic aberrations, while the rear elements flatten the field. Its 50-mm corrected image circle is compatible with full-frame sensors.<\/p>\n<h3>Compatibility and Installation<\/h3>\n<p>The tube comes with a rack-and-pinion focus mechanism, an MEF 1:8 gear ratio, a rotating collar, and standard fittings, including the M72-M48 CMOS adapter and the 31.7 mm eyepiece adapter. The retractable dew shield reduces the length to 486 mm for transport. Mounting clamps, the mount, the viewfinder, eyepieces, and the camera are selected separately. For photography, the M48 \u00d7 0.75 output provides a 55 mm focal length to the sensor. An M54 camera uses the optional TKA00201 adapter; a camera with interchangeable lenses requires adapters specific to its bayonet mount. For observation with the Takahashi 31.7 MC prism, the manufacturer recommends the TKA00548 prism corrector to maintain performance.<\/p>\n<h3>Accessories for Your System<\/h3>\n<ul>\n<li><a href=\"https:\/\/deep-space-astronomy.ch\/en\/product\/takahashi-tka11420\/\">Double Clamps for FCT-65D\/FS-60CP\/FC-76DP\/FSQ-80FC (95 mm diameter) (TKA11420)<\/a> : optional accessory, sold separately.<\/li>\n<\/ul>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>80 mm apochromatic telescope with a focal length of 450 mm, double-fluorite quintuplet with a 50 mm image circle.
