Airy Disk APO 106mm f/6.6 Triplet FCD-100

Superior Contrast, Stunning Optical Power

The Airy Disk APO 106mm f/6.6 Triplet is engineered for astronomers who refuse to compromise on contrast, brightness, or clarity. With its slightly over 4-inch aperture, this refractor strikes the perfect balance between portability and exceptional optical performance—making it a versatile choice for both astrophotographers and visual observers.

At its core is a premium triplet objective built with Hoya FCD-100 extra-low dispersion glass, one of the finest ED materials available. This Japanese-crafted glass nearly eliminates chromatic aberration, resulting in razor-sharp stars, crisp planetary detail, and beautifully accurate color. Whether you're capturing deep-sky images or studying the planets at high magnification, the 106mm APO delivers professional-grade results.

Its f/6.6 focal ratio provides an excellent blend of light-gathering power, contrast, and versatility—ideal for detailed lunar and planetary views as well as high-quality imaging of galaxies, nebulae, and clusters. With robust mechanical construction and precision focusing, this telescope performs reliably in the field and integrates seamlessly into advanced imaging setups.

Perfect for:

• High-contrast planetary and lunar observing

• Deep-sky astrophotography

• Intermediate to advanced astrophotographers

• Users seeking more brightness and resolution than 80–100mm class refractors
