FS-60Q Fluorite Refractor w/ CQ Module
Takahashi
The Takahashi FS-60Q is a premium ultra-portable fluorite apochromatic refractor that combines a versatile modular design with exceptional optical performance for planetary, lunar, and eclipse imaging. With the integrated CQ 1.7x module, this 60mm refractor transforms from a fast f/5.9 wide-field scope (355mm focal length) into an f/10 planetary instrument (600mm focal length) with a flat field across the image circle, making it ideal for high-contrast lunar and planetary observation as well as eclipse photography. The fluorite optics deliver outstanding image contrast and color fidelity while remaining compact and lightweight enough for backpack-style transport and airline travel, making it a favorite tool for eclipse chasers and dedicated astrophotographers seeking maximum versatility in minimal space.
