PRODUCT DESCRIPTION
Takahashi FSQ-85EDX is a compact, high-end astrograph designed for precision wide-field imaging with full-frame sensors. Known as the “Baby Q,” this portable refractor delivers premium performance in a travel-ready design — making it a favorite for astrophotographers on the move.
- Perfect for experienced astrophotographers seeking full-frame compatibility and contrast-rich imaging
- Four-element Petzval design provides a naturally flat field without additional flatteners
- ED glass elements offer superb color correction across UV to near IR, ensuring pinpoint star sharpness
- Long 56 mm back focus supports a wide variety of medium format CCDs and binoviewers
- Optional field flattener expands the corrected image circle from 28 mm to 44 mm, ideal for full-frame sensors
- Newly designed 78 mm heavy-duty focuser includes camera angle adjuster and supports heavier payloads
- Knife-edge internal baffles eliminate off-axis light, enhancing image contrast
- Travel-sized tube collapses to 12.68 inches and weighs under 9 lbs for airline portability
- Engineered for stability and durability with premium mechanical components
The FSQ-85EDX is engineered specifically for digital imaging, offering a rare combination of optical performance, build quality, and transportability. Whether used from a home observatory or a mountaintop sky site, this system performs consistently at the highest imaging standards.
