Takahashi FSQ-80FC Refractor Telescope
A Legendary Astrograph — Now in a Portable 80mm
The FSQ-80FC brings Takahashi’s legendary FSQ astrograph design into a compact and highly portable 80 mm platform. With a 450 mm focal length and fast f/5.6 optics, it delivers sharp stars and a flat field across modern full-frame sensors while remaining lightweight enough for travel imaging setups.
Designed for both astrophotography and premium visual observing, the FSQ-80FC combines Takahashi’s fluorite optics with a new five-element optical system optimized for modern CMOS cameras.
Key Features
- 80 mm fluorite apochromatic astrograph
- 450 mm focal length (f/5.6)
- 5-element optical design with two fluorite elements
- Large 50 mm image circle for full-frame cameras
- Compact, travel-friendly tube design
- Precision Takahashi mechanical construction
Optimized for Modern Astrophotography
The FSQ-80FC is designed with today’s imaging systems in mind. Removing the M48 adapter reveals a standard M48 interface with 55 mm backfocus, allowing many cooled CMOS cameras to attach directly without additional spacers.
Optional adapters support larger M54 camera threads and DSLR / mirrorless cameras, making the FSQ-80FC a flexible imaging platform.
Optical Design
The five-element optical design combines a front fluorite doublet with a rear field-flattening group. The result is exceptional center sharpness and a flat, evenly illuminated field ideal for wide-field astrophotography.
