FOA-60Q: A Refractor That Achieves Extreme Aberration Correction!
The Takahashi FOA-60Q is a compact powerhouse that proves big performance can come in a small package. This 60 mm apochromatic (APO) fluorite doublet delivers a 530 mm focal length in an ultra-portable design, perfect for grab-and-go observing or travel setups. The FOA-60Q version includes the dedicated 1.7X extender, boosting the focal length to 900 mm for increased magnification and even tighter star images. It’s the kind of scope that fits easily in your car — yet punches far above its weight under the stars.
What truly sets the FOA-60Q apart is its optical precision. The carefully spaced doublet elements deliver spherical correction comparable to Takahashi’s legendary TOA series, resulting in a Strehl ratio exceeding 96% — and an astonishing 99%+ with the extender installed. That means razor-sharp stars, exceptional contrast, and beautiful color correction for both visual observers and astrophotographers. With a generous 44 mm image circle, it’s fully capable of full-frame imaging, and for even flatter fields across the sensor, the optional 0.93x flattener (sold separately) completes this remarkably refined optical system.
