Thanks to the longer focal lenght (800 mm) than the standard FC-100DC/DF and thank to the optimization of the optical design including now an high-refarctive index front lens that perfectly matches the reat fluorite element, this new Takahashi apochromatic doublet shows a perfect color correction and it offers wonderful high magnification views of the Moon, planets and double stars. Thanks to the optional optical accessories it can be transformed into a powerful and fast astrograph. Much like all the FC series, the optical tube is very light, only 3.8 Kg.
The Takahashi FC-100DZ is compatible with the optional digital focal reducer FC-35 0.66x that transforms the instrument in fantastic 530 mm focal length astrograph with a fast F/5.3 focal ratio. The FC-100DZ can be also equipped with the latest 1.04x Multi-Flattener that takes focal length up to 820 mm (F/8.2) for higher resolution imaging. Both optical corrector have a wide imaging circle of 44 mm.
