Takahashi FS-60Q F/10 Fluorite Doublet Apo Refractor Telescope
The Takahashi FS-60Q apochromatic refractor is a longer focal length version of the FS-60CB. It is in fact the same telescope to which is added the Extender 1.7X kit which allows to change the FS-60CB to F/D 10, by making it evolve towards a formula with 4 lenses offering a flat field on the whole image circle.
The longer F/D ratio allows optimal chromatic correction for unforgettable planetary observations or for eclipse photography. It is quite possible to remove the 1.7X extender and switch from an FS-60Q to an FS-60CB, at F/5.9 more suitable for deep sky imaging. The same refractor allows you to quickly change from a 600 mm focal length to a 355 mm focal length according to your needs.
