Airy Disk APO 140mm f/6.5 Triplet FCD-100 Apochromatic Refractor

The Airy Disk 140mm Apochromat is a premium refractor for small home observatories, astrophotographers, and visual observers who want superior image quality from a larger instrument.

Its substantial aperture excels at light collection, while the triplet lens uses Japanese Hoya FCD100 ED glass to deliver sharp, low-distortion views. The 140mm f/6.5 design is well suited for deep-sky imaging, high-contrast observing, and close double-star work.
