The FS-60CP uses the same two-element fluorite apochromatic objective as Takahashi's long-running FS-60CB, in a body built for imaging. Its large M64 × 0.75 focuser and long back focus make it compatible with the dedicated 60CP FU Reducer 0.65×, which turns it into a 230 mm f/3.8 astrograph covering a 44 mm image circle.
The air-spaced doublet objective puts a fluorite element at the front for sharp, high-contrast, colour-free images. At prime focus the telescope has a 355 mm focal length at f/5.9.
The FS-60CP works with the current FS-series correctors as well as its dedicated reducer:
Because of its long back focus, the FS-60CP will not reach infinity focus on its own. For visual observing, Takahashi specifies a 50.8 mm diagonal mirror, a 31.7 MC diagonal prism or a 50.8 extension tube, sold separately. A 6×30 finder is recommended and sold separately.
