It is equipped with a 31.75 mm compact rack-and-pinion focuser, inherited from the FS-60CB. It is much lighter than its big sister FC-100DF, only 2.8 kg compared to 3.6 kg for the FC-100DF. A small mount will be enough to make the most of it. Designed primarily for observation, it still allows the use of small cameras in astrophotography.\u003c\/p\u003e\n\u003cp\u003ePhotography at the native focal length of the refractor requires the 76D field corrector (or the multi-flattener).
