The FSQ-80FC combines an 80 mm aperture with a 450 mm focal length for wide-field deep-sky imaging and visual observation. Its five-element, five-group lens design includes two fluorite elements to correct chromatic aberrations, while the rear elements flatten the field. Its 50-mm corrected image circle is compatible with full-frame sensors.
The tube comes with a rack-and-pinion focus mechanism, an MEF 1:8 gear ratio, a rotating collar, and standard fittings, including the M72-M48 CMOS adapter and the 31.7 mm eyepiece adapter. The retractable dew shield reduces the length to 486 mm for transport. Mounting clamps, the mount, the viewfinder, eyepieces, and the camera are selected separately. For photography, the M48 × 0.75 output provides a 55 mm focal length to the sensor. An M54 camera uses the optional TKA00201 adapter; a camera with interchangeable lenses requires adapters specific to its bayonet mount. For observation with the Takahashi 31.7 MC prism, the manufacturer recommends the TKA00548 prism corrector to maintain performance.
The Takahashi FSQ-80FC is an 80-mm-aperture, flat-field quintuplet refractor with two fluorite elements and a focal length of 450 mm (f/5.6), designed primarily for deep-sky astrophotography. Its focal length is ideal for observing large nebulae such as the North America Nebula, the Rosette Nebula, and the Heart and Soul Nebula, as well as the entire Andromeda Galaxy and the Pleiades with their nebular features. With a fast f/5.6 aperture, it allows for reasonable exposure times even when using narrow-band filters.
With an APS-C camera featuring 3.76 µm pixels (Sony IMX571 sensor), you get approximately 1.72″ per pixel for a field of view of 3° × 2°. The 50 mm image circle covers full-frame sensors (24 × 36 mm): a full-frame mirrorless camera will also work.
No. Its optical design (a quintuplet with two fluorite elements and a flat field) inherently produces a flat field, with sharp stars all the way to the corners, without the need for an external field-flattener.
55 mm from the M48. This distance is measured from the thread to the sensor, including the rings, filter wheel, and filter wheel assembly: adhering to this measurement down to the millimeter ensures that the stars remain round in the corners.
The tube weighs about 4.1 kg; with the camera, filter wheel, and guide scope, expect it to weigh around 5.6 kg: an HEQ5-R Pro-class mount provides plenty of headroom. A refractor requires no collimation: once balanced, it’s ready to use as soon as it reaches operating temperature. At 48.6 cm long, it fits easily in the trunk.
Yes, as a bonus: with an angled mirror and an eyepiece, it provides high-contrast images without false colors of the Moon, the planets, and double stars.
Here are a few accessories we've selected for this model, depending on your needs.
Pair of Takahashi 95WB collars for the FSQ-80FC. The 220B dovetail is sold separately. Check the mounting clearance; spacers may be required.
Vixen Takahashi 220B dovetail for 95WB clamps, sold separately. Check the grip, clearance, and balance.
Optional top plate for Takahashi 95WB mounts, allowing you to attach accessories. Mounts and dovetails sold separately; check for balance and clearance—spacers may be required.
Optional M72–M54 male adapter for the M54 CMOS camera. The M72–M48 CMOS connector is already included with the FSQ-80FC; this is a different configuration. Check the connectors and measure 55 mm from the M54 shoulder.
Optional M72–M54 female camera adapter for the DX-WR ring compatible with the camera mount; sold separately. Check the connections and measure 56.2 mm from the rear face of the M54. Alternative to the included M48 CMOS mount.
Takahashi 95S one-piece clamp, sold separately; an alternative to the 95WB double clamps. It protrudes beyond the tube’s cross-section and prevents the dew shield from retracting completely. Check the mounting and balancing; Takahashi recommends using a separate KB-S plate.
Optional Takahashi KB-S plate for offsetting the 95S clamp and facilitating balancing of the FSQ-80FC; clamp and plate sold separately. Check the fit on a Takahashi EM-11 or EM-200 mount. The 95S limits the full retraction of the dew shield.
