The Explore Scientific FCD100 80mm Refractor is a premium air-spaced triplet apochromatic refractor telescope for astrophotography, built around genuine HOYA FCD100 extra-low-dispersion glass — comparable to Ohara FPL-53 — for outstanding color correction, pinpoint stars, and true, high-contrast color.

This bundle adds a matched field flattener that keeps stars sharp all the way into the corners of your frame at the scope's native f/6 (480mm) — exactly what wide-field deep-sky imaging demands.

Who it's for

Astrophotographers and serious hobbyists who want a portable, high-end 80mm apo with flat-field, edge-to-edge sharpness. This is an optical tube with flattener — a mount and camera are sold separately. Getting into imaging? See our astrophotography for beginners guide.

Frequently asked questions

What does the field flattener do?
It corrects the natural curvature of the focal plane so stars stay sharp in the corners, not just the center — essential for clean wide-field astrophotos. It keeps the native f/6 focal ratio.

Field flattener or focal reducer — which should I choose?
A flattener keeps native f/6 for the flattest field and true focal length; a 0.8× reducer speeds the scope to f/4.8 for shorter exposures and a wider field. Choose the flattener for framing/scale, the reducer for speed.

How is FCD100 different from standard ED glass?
HOYA FCD100 is a premium ED glass comparable to Ohara FPL-53, giving even better color correction and contrast than ordinary ED optics.

Is a mount included?
No — this is the optical tube plus flattener. You'll need a tracking equatorial mount and a camera for imaging.
