Sky-Watcher Evostar 80ED

The classic first imaging refractor: an 80mm ED doublet that shows clean, colour-controlled stars for a fraction of a triplet apo. The scope that has launched more astrophotographers than any other.

What it's built forOpen these in the simulator →

This telescope was built for your first nights out.

Light, simple, and forgiving — it shows the Moon, the bright planets, and the showpiece clusters without a manual. The kind of scope that actually gets used, because it is easy to carry out and easy to point.

The view people remember

The Pleiades, blue and blazing.

A knot of hot young stars wrapped in the faintest haze of reflected light — best at the lowest power, where the whole cluster drops into a single glittering field.

01What it's good at

What it's best at — and the trade-offs.

An FPL-53 ED element controls most false colour, so stars image far cleaner than a cheap achromat.
Best at
✓An FPL-53 ED element controls most false colour, so stars image far cleaner than a cheap achromat.
✓At 80mm f/7.5 it is small, light and forgiving, an ideal first scope on a modest tracking mount.
✓A dual-speed Crayford focuser holds a camera and nails fine focus.
✓Endlessly supported: reducers, flatteners and rings are cheap and everywhere.
Trade-offs
!A doublet leaves a trace of blue-violet halo on the brightest stars.
!Needs a field flattener for corner-sharp stars on a camera (sold separately).
!OTA only, a tracking mount and camera are extra.
!80mm is a wide-field tool, not a light bucket for small faint targets.
02In plain English

What These Numbers Mean

80mm · f/7.5 · 600mm FL
Aperture
80 mm
Three inches of ED glass, about 23 percent more light than a 72 mm. It handles the Moon and planets pleasantly at moderate power and has enough grasp for real deep-sky imaging with patient integration.
Focal length
600 mm
A middle field length that frames the Orion Nebula, M31's core, the Eagle or the larger galaxies with useful scale, while still fitting many of the bigger nebulae on APS-C.
Focal ratio
f/7.5
Moderate speed. Exposures are longer than a fast astrograph needs, but tolerances on focus, spacing and tilt are far more forgiving, which suits someone still learning the workflow. A 0.85x reducer is the common upgrade.
Optical design
ED doublet apochromat
One ED element removes nearly all the visible colour error, so stars stay tight and white in both eyepiece and camera. The doublet cools quickly and holds its alignment indefinitely.
Weight
3 kg tube
About 6.6 lb. A small equatorial or a well-loaded star tracker carries it, and it fits easily in a case for travel.
Mount
OTA only
You supply the mount. At 600 mm, autoguiding starts to matter, so a mount with a guider port is a better long-term choice than a bare tracker.

Editor’s Take

The Evostar 80ED is a classic first imaging refractor. It is an "ED doublet": a two-element lens using low-dispersion (ED) glass that suppresses the colour fringing cheap refractors add to bright stars, so stars image as clean points, the near-"apo" correction that makes a scope good for photography. At 80 mm it frames larger nebulae and galaxies and stays light enough for a modest tracking mount. Sold as an OTA (tube only, no mount), it wants a matched field flattener for corner-sharp stars, and delivers most of a premium apo's clean stars for far less.

Star Cluster Sweeper

Featured

Ultra-wide-field setup for large star clusters and sweeping the Milky Way. The 80ED and the Panoptic 35mm give just under 4° of true field — wide enough to hold the Double Cluster, the Pleiades and long stretches of the summer Milky Way whole, at a 4.7mm exit pupil that stays comfortable under a dark sky. The Twilight I is a manual alt-azimuth on a steel tripod, which is exactly what sweeping wants: you push the scope along the star clouds and stop when something catches your eye.
