The Takahashi FSQ-80FC Astrograph Telescope brings Takahashi’s legendary FSQ astrograph performance into a compact, travel-ready 80mm platform—perfect for serious astrophotographers and discerning visual observers alike. Designed with portability and precision in mind, this premium refractor delivers exceptional image quality without the bulk of larger imaging systems.

With a fast 450mm focal length and f/5.6 focal ratio, the FSQ-80FC captures wide-field deep-sky objects with stunning clarity, producing pinpoint stars and a remarkably flat field across today’s full-frame sensors. Its advanced five-element optical system, featuring dual fluorite elements, is specifically optimized for modern CMOS cameras, ensuring outstanding color correction, contrast, and edge-to-edge sharpness.

Whether you're building a lightweight travel imaging rig or upgrading to a high-performance wide-field astrograph, the FSQ-80FC offers the perfect balance of optical excellence and mechanical precision that Takahashi is known for.

• 80mm fluorite apochromatic astrograph for superior color correction
• Fast 450mm focal length (f/5.6) ideal for wide-field astrophotography
• Advanced 5-element optical design with dual fluorite elements
• Large 50mm image circle supports full-frame and large-format sensors
• Compact, lightweight tube perfect for portable imaging setups
• Precision-engineered Takahashi construction for long-term reliability

The Takahashi FSQ-80FC Astrograph Telescope is purpose-built for seamless integration with modern astrophotography setups, making it an exceptionally versatile choice for today’s imaging workflows. Engineered with current-generation CMOS sensors in mind, this compact astrograph simplifies your imaging train while maintaining Takahashi’s renowned optical precision.

By removing the included M48 adapter, users gain access to a native M48 interface with an industry-standard 55mm backfocus. This allows many popular cooled CMOS astronomy cameras to connect directly, often eliminating the need for additional spacers or complex adapters. The result is a cleaner, more rigid imaging setup that minimizes flexure and maximizes performance across the entire image field.

For astrophotographers looking to expand their system, the FSQ-80FC supports a wide range of optional adapters. These include larger M54 thread compatibility for high-end imaging cameras and accessories, as well as dedicated solutions for DSLR and mirrorless cameras. This flexibility ensures the telescope can evolve alongside your equipment, whether you’re upgrading sensors or refining your imaging train.

With its user-friendly backfocus design and broad compatibility, the FSQ-80FC stands out as a future-proof imaging platform, ideal for capturing deep-sky targets with precision, efficiency, and minimal setup complexity.

The Takahashi FSQ-80FC Astrograph Telescope features a sophisticated five-element optical design engineered to deliver uncompromising performance for modern astrophotography. At its core is a premium front-mounted fluorite doublet, paired with a precisely matched rear field-flattener group that works in harmony to produce outstanding image quality across the entire frame.

This advanced optical configuration ensures exceptional on-axis sharpness while simultaneously maintaining a flat, evenly illuminated field from center to edge, critical for today’s high-resolution, full-frame imaging sensors. Stars remain tight, round, and color-accurate across the entire image circle, eliminating the need for additional field flatteners or corrective optics.

The result is a true wide-field astrograph capable of capturing expansive nebulae, dense star fields, and sweeping nightscapes with remarkable clarity, contrast, and consistency, making the FSQ-80FC a top-tier choice for astrophotographers who demand precision and ease of use in a compact form factor.
