This Explore Scientific ED 80mm APO astrophotography kit bundles a triplet apochromatic refractor telescope with a 0.8x focal reducer and the computerized iEXOS-100 GoTo mount — everything you need to start imaging the deep sky except the camera. The ED triplet uses extra-low-dispersion glass to focus colours precisely for sharp, colour-true stars, while the 0.8x reducer speeds up and widens the optics for faster, larger-field exposures.

With an 80mm aperture and 480mm focal length (f/6), the 0.8x reducer takes it to roughly 384mm at f/4.8 — bright and wide for capturing large nebulae and galaxies. The iEXOS-100 is a portable WiFi GoTo German equatorial mount that automatically finds and tracks targets through long exposures.

Who it's for: Astrophotographers who want a fast, wide-field, complete imaging rig in one kit. Learn the fundamentals in our beginner's guide to astrophotography.

  • ED triplet APO optics: extra-low-dispersion glass for sharp, colour-accurate images.
  • 0.8x focal reducer: speeds the system to about f/4.8 and widens the field for faster imaging.
  • 80mm f/6 native: 480mm focal length, ~384mm with the reducer fitted.
  • iEXOS-100 GoTo mount: WiFi equatorial mount that finds and tracks objects automatically.
  • Complete imaging kit: OTA, reducer and tracking mount ready to shoot.

What you'll see: With the reducer fitted this fast, wide field excels on large deep-sky targets — sprawling nebulae, big galaxies and rich star clusters — captured brightly and framed generously, with the GoTo mount tracking steadily. Visually, the ED80 also gives crisp, colour-true views of the Moon, planets and star fields.

What does the 0.8x reducer do?
It shortens the focal length and speeds the focal ratio, so you capture a wider field and gather light faster — shortening the exposures needed for deep-sky targets.

Is this a complete astrophotography setup?
Almost — it includes the ED triplet OTA, the 0.8x reducer and a GoTo tracking mount. You add a camera and the appropriate adapter.

What does the iEXOS-100 GoTo mount do?
It automatically slews to objects and tracks them as the sky moves, which is essential for long-exposure imaging.

Reducer or flattener — what's the difference?
A flattener corrects field curvature at the native focal length; a reducer also shortens focal length for a faster, wider field. This kit includes the 0.8x reducer.

Frequently Asked Questions

With a beginner telescope you can see a surprising amount — the craters and mountains on the Moon, the rings of Saturn, the moons of Jupiter, and star clusters like the Pleiades. As you get more comfortable, you can also spot nebulae and distant galaxies. Not sure which beginner telescope is right for you? Check out our Telescope Buying Guide.
