The Explore Scientific ED80 Essential Series Refractor is an 80mm f/6 air-spaced triplet apochromatic refractor telescope — a portable, astrophotography-grade scope that delivers pinpoint stars with very little false color. Its air-spaced triplet lens uses genuine HOYA ED glass for crisp, high-contrast views and images at a friendly price.

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) — ideal for wide-field deep-sky astrophotography.

Who it's for

Keen beginners and up who want genuine apochromatic optics with flat-field, edge-to-edge sharpness for astrophotography. 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.

What does apochromatic triplet mean?
It's a premium three-lens design that brings colors to a common focus, so stars look sharp and true rather than fringed — a real step up from doublet and achromatic refractors.

How is this different from the FCD100 version?
Same 80mm f/6 triplet layout, but the FCD100 version uses higher-grade HOYA FCD100 glass for even better correction. The Essential ED gives excellent results for less.

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