Reference TFA06110
The Takahashi FOA-60Q combines a 60-mm apochromatic fluorite doublet with the built-in EXQ1.7XR extender. The focal length reaches 900 mm at f/15: this configuration is ideal for visual observation with a long focal length, while maintaining a 60 mm aperture. Part number TFA06110 refers to the Q-version tube alone.
The extender is included in the optical kit. With it, Takahashi specifies a corrected image circle of 44 mm and a back focus of 208.1 mm. The FOA-60Q configuration allows you to set up visual or photographic setups depending on the accessory selected. The extender can be removed to return to the FOA-60 configuration by following the instructions.
The air-gap objective features a front fluorite element and is coated with a hard multilayer coating. Focusing is achieved using an FS-60-type rack-and-pinion mechanism. The tube is 702 mm long and 68 mm in diameter, with a retractable dew shield for storage.
Takahashi FOA-60Q optical tube only, part number TFA06110, with built-in EXQ1.7XR extender. No additional conversion kit is required to achieve the Q configuration. The mount, finder scope, mounting collar, and right-angle mirror must be selected separately.
Manufacturer's part number: TFA06110. Takahashi's Official Profile.
The Takahashi FOA-60Q is a fluorite doublet refractor with a built-in 60-mm aperture Q-extender, providing a focal length of 900 mm (f/15). This long focal ratio makes it ideal for high-resolution imaging of the Moon, planets, and the Sun in white light (using a full-aperture solar filter), as well as for observing close binary stars.
A fast planetary camera with 2.9 µm pixels is well-suited for f/15: the sampling size drops to about 0.66″ per pixel, which takes full advantage of the lens’s resolution (1.93″) without an additional Barlow lens. Record short videos and stack the best frames.
Yes, that's a nice bonus: high-contrast images of the Moon, the planets, and double stars, up to about 120×. Like any refractor, it requires no collimation.
Yes: The tube weighs about 2.1 kg and is 70.2 cm long, so a small mount is sufficient.
Here are a few accessories we've selected for this model, depending on your needs.
Takahashi 68S-GT collar compatible with the FOA-60Q tube. Be sure to use a lower interface that is compatible with the mount and the collar's mounting holes.
1.5× ED Extender for FOA-60Q: 1,350 mm at f/22.5 for visual observation. For a flat photographic field, keep the built-in 1.7×R extender in place; check the connections and assembly, and do not place a filter at the eyepiece end of the extender.
80 mm heating strip for an 80 mm defogger. Check its location and clearance; a 12 V power supply or controller with an RCA connector and sufficient power must be provided separately.
80 mm motorized flat panel recommended by Wanderer for the FS-60/FOA-60 series. Measure the outer diameter and check the mounting, centering, and clearance.
For a Takahashi EM-11 or EM-200 mount, this S-series base plate is compatible with the 68S-GT symmetrical clamp, sold separately. Check the M8 screws, mounting, load, and balance; this is not a Vixen tail.
Recommended diameter: 150 mm. Check the measurement and the mounting.
