Explore Scientific FCD100 Triplet APO

Carbon fiber is exceptionally stable, meaning it resists thermal expansion and contraction much better than metal tubes. This ensures your focus remains locked throughout long imaging sessions, even as temperatures drop at night.

It is designed to excel at both. The high-quality triplet optics provide the color correction needed for crisp visual views, while the robust 2.5-inch hexagonal focuser and lightweight design make it a capable platform for serious astrophotography.

Yes, the hexagonal design is specifically engineered to handle heavier imaging payloads without slipping or sagging. It provides a more rigid connection than standard rack-and-pinion focusers, which is critical for maintaining sharp focus during long exposures.

FCD100 is a premium extra-low dispersion glass that virtually eliminates chromatic aberration. You will see high-contrast images with true-to-life colors, free from the purple fringing often seen around bright stars in lesser refractors.

At just 9.3 pounds, this is an excellent grab-and-go instrument. Its lightweight carbon fiber construction makes it easy to mount on smaller, portable tracking mounts without sacrificing optical performance.

It includes the optical tube, a cradle ring with a handle, a Vixen-style dovetail plate, and a high-reflectivity diagonal. You will still need to provide your own eyepieces and a compatible telescope mount to begin observing.
