Explore Scientific FCD100 Series Refractor Telescope

FCD100 is a high-grade extra-low dispersion glass that provides superior color correction compared to standard ED glass. It effectively minimizes chromatic aberration, ensuring that bright stars and planetary edges appear crisp without distracting color fringing.

Yes, it is designed with astrophotography in mind. The air-spaced triplet design and the robust 2.5-inch HEX focuser provide the stability and optical precision needed to support heavy imaging cameras and accessories for long-exposure work.

Thanks to its carbon fiber construction, the tube weighs only 14 pounds. This makes it significantly easier to transport and mount than traditional metal-tube refractors of the same aperture, without sacrificing the rigidity needed for sharp images.

This telescope uses a Vixen-style dovetail, which is compatible with most standard equatorial and alt-azimuth mounts. Given the 127mm aperture and the potential for heavy imaging gear, you will want a sturdy mount capable of handling its 41.75-inch length and payload weight.

Carbon fiber is an excellent choice for telescopes because it has a very low coefficient of thermal expansion. This means the tube maintains its shape and focus better than metal tubes as temperatures fluctuate throughout the night, reducing the need for constant refocusing.
