ZWO FF80 Quadruplet Apochromatic Refractor Telescope

The ZWO FF80 Quadruplet is a highly compact, high-performance apochromatic refractor designed specifically for premium astrophotography and high-magnification visual observation. Featuring a flat-field optical design, this telescope eliminates the need for a separate field flattener, making it an exceptional choice for astrophotographers seeking flawless edge-to-edge tracking across full-frame sensors. SkyHunters is one of the leading telescope suppliers, offering professional consultations and high-quality customer support.

Key advantages

• Quadruplet optical design with two ED lenses for superior chromatic aberration suppression.

Product description

The ZWO FF80 Quadruplet features an aperture of 80 mm, a focal length of 600 mm, and a focal ratio of f/7.5. Thanks to its advanced four-element design containing two extra-low dispersion (ED) glass elements, it provides outstanding color correction and contrast. The integrated flattener is a major practical benefit for astrophotography, ensuring pinpoint stars across the entire sensor frame without the hassle of calculating separate sensor-to-flattener spacing.

The telescope comes fully equipped for immediate integration into your imaging rig, featuring an extendable dew shield, a Vixen/GP finder shoe, sturdy tube clamps, a Vixen-style dovetail rail, and a convenient carrying handle. The optical tube assembly (OTA) weighs just 3.9 kg (4.7 kg with clamps and rail included), making it highly compatible with medium-sized equatorial mounts.

Precise backfocus distances for the included adapters:

• 115 mm from M48x0.75 external thread
• 135 mm from M54x0.75 external thread
• 155 mm from M68x1 external thread
