FC-100DZ Fluorite Refractor

The FC-100DZ is Takahashi's latest Steinheil fluorite doublet refractor, featuring a pairing of fluorite with exotic low-dispersion glass that delivers exceptional performance across the entire visible spectrum. With a Strehl ratio exceeding 97.6% and minimal chromatic aberration, it excels for both lunar/planetary observation and astrophotography, offering outstanding views at high magnifications while maintaining excellent color correction even in blue wavelengths. The compact, 3.8 kg optical tube assembly features a retractable dew shield and rapid thermal stabilization, making it an ideal all-rounder for visual observers and imagers seeking premium optical quality in a portable 100mm refractor.
