Explore Scientific FCD100 80mm APO Triplet + 0.8× Reducer + iEXOS-100 GoTo Mount — Wide-Field Astrophotography Bundle

The Explore Scientific FCD100 80mm APO triplet refractor telescope with 0.8× reducer and iEXOS-100 GoTo mount is a complete wide-field astrophotography bundle. An apochromatic (APO) triplet uses three lens elements — here with premium Hoya FCD100 extra-low-dispersion glass — to focus all colors of light together for sharp, high-contrast, false-color-free images, while the matched 0.8× reducer widens and flattens the field and speeds up the optics for shorter exposures.

This package pairs the 80mm f/6 triplet (reduced to roughly f/4.8) with the iEXOS-100 PMC-Eight GoTo mount, which finds and tracks targets automatically over WiFi or Bluetooth — giving you optics, corrector, and mount in one portable rig.

Who it's for

Ideal for beginner-to-intermediate astrophotographers who want a portable, high-quality wide-field imaging setup in a single purchase. New to the hobby? See our guide on how to pick your first telescope.

Key features

• FCD100 air-spaced triplet APO with Hoya ED glass for false-color-free sharpness.
• 80mm f/6 optics (480mm focal length) suited to nebulae and large deep-sky targets.
• 0.8× focal reducer included for a wider, flatter, faster field (about f/4.8).
• iEXOS-100 PMC-Eight GoTo mount with WiFi/Bluetooth automated slewing and tracking.
• Portable, complete imaging rig combining optics, corrector, and mount.

What you'll see

With wide, flat, well-corrected optics, this refractor excels on large deep-sky objects — emission nebulae like Orion and the North America Nebula, big star clusters, and sweeping Milky Way fields. On the tracking mount you can record long-exposure images that reveal faint nebulosity invisible to the eye, and views of the Moon and bright planets stay crisp and free of color fringing.

Frequently asked questions

What does the 0.8× reducer do?
It shortens the focal length to about 384mm (f/4.8), giving a wider field of view, flatter stars across the frame, and faster exposures — ideal for large nebulae.

Is this a complete imaging kit?
It includes the optics, reducer, and GoTo mount. You'll still need a camera (and usually a T-ring/adapter) to begin imaging.

Do I need a computer for the mount?
No hand controller is required — the PMC-Eight connects over WiFi or Bluetooth to Explore Scientific's free app on your phone, tablet, or PC.
