Explore Scientific Apochromatic refractor AP 102/714 ED FCD-100 CF Hexafoc OTA (60236)

FCD-100 Optical Apochromatic Refractor: The Gold Standard in Small to Medium Apertures

The FCD-100 optical apochromats set the benchmark for small and medium-sized aperture telescopes. These three-element apochromats, featuring special FCD-100 glass by Hoya, Japan, establish a new standard for color purity in their price range. With an impressive polystrehl value of 0.97, the optical design achieves exceptionally high correction.

Versatile Performance
This exceptional apochromat excels in various astronomical applications:

• Fast aperture ratio for quick astrophotography exposures

• High image quality and contrast for broad observations

• Ultra-clear planetary views

Compact and Lightweight Design

• Carbon fiber tube ensures lightweight portability

• Retractable dew cap for compact storage and transportation

Premium Focuser
A high-quality 2.5" Hexafoc drawtube with 1:10 reduction complements the superior optics. Its large free diameter prevents vignetting with larger camera sensors, a common issue with smaller focusers.
