70×
Saturn at 70× in 72 mm — exit pupil 1.0 mm, Bortle 6 sky. Computed, not photographed.

72–80 mm ED refractor

Sky-Watcher Evostar 72 EDX

A small, very well corrected refractor. Modest aperture bought at a high price per millimetre, in exchange for images with no false colour and a second career as an imaging telescope.

Should you buy it?

  • Yes if what you mainly want is first astrophotography, serious deep-sky imaging, taking it with me: that is what this family does best.
  • No if your priority is nebulae, clusters and galaxies, by eye: other families do better for the same money.
  • The price is for the tube alone; add a mount before you compare.

Computed from its family's per-goal scores and its own numbers — not a rating, not one evening's opinion.

What it shows, really

These circles are simulations, computed from the aperture, the magnification and the sky — indicative, not exact. A real night also depends on the turbulence, your eyes and your experience. Closer to the truth than the photo on the box; still not a promise.

Under a suburban sky (Bortle 6), through a common 25 mm eyepiece for wide targets and a 10 mm for planets. Every circle is the true field — nothing is enlarged.

Made for

  • First astrophotography

    The standard first imaging telescope, and it stays useful for years.

  • Serious deep-sky imaging

    Small, forgiving of mount error, and short enough to guide easily.

  • Taking it with me

    The whole setup fits in a rucksack and a small case.

  • The Sun

    In white light: sunspots with their penumbra, faculae near the edge, and granulation on a steady morning. Dawes' limit on the Sun: 1.6″ (116 ÷ 72 mm, arithmetic). Measure the outside diameter first, then one of: Omegon Helievo 72 (64–88 mm), Omegon Helievo 92 (84–108 mm), Omegon Helievo 112 (104–128 mm) (€55–€69). Every time: certified filter over the front · finder capped · never an eyepiece filter · an adult with children · never without the filter · measure first.

Not made for

  • Nebulae, clusters and galaxies, by eye

    Wide-field sweeping is lovely; faint galaxies are not on the menu.

The Sun, safely

No solar filter in the box

The Sun with this model

No source we have states the outside diameter of its tube or dew shield. Measure it at the front, then take the cell whose range holds it. For 72 mm of aperture, one of these:

In white light: sunspots with their penumbra, faculae near the edge, and granulation on a steady morning. Dawes' limit on the Sun: 1.6″ (116 ÷ 72 mm, arithmetic).

  • Omegon Helievo 72 (64–88 mm): holds 64–88 mm, €55 (seen 26 Sept 2026) Astroshop
  • Omegon Helievo 92 (84–108 mm): holds 84–108 mm, €59 (seen 26 Sept 2026) Astroshop
  • Omegon Helievo 112 (104–128 mm): holds 104–128 mm, €69 (seen 26 Sept 2026) Astroshop

The listing names no standard; no international standard exists for filters on telescopes, binoculars or lenses (AAS).

Every time

  • A certified solar filter over the FRONT of the instrument, fastened so it cannot slip or blow off.
  • Cap or remove the finder. It is a second telescope, and it has no filter.
  • Never a filter at the eyepiece end: the concentrated sunlight there can crack it in an instant.
  • With children, an adult is there every time.
  • Never look, or point, without the filter on. Check it before each use; a scratched or torn filter goes in the bin.
  • Measure before ordering. A cell that sits loose can fall off.
Sources for the Sun

The family it belongs to: 72–80 mm ED refractor

What it does well

  • No colour fringing worth the name — the view is clean in a way small achromats are not
  • Light enough for a modest mount, which keeps the whole setup portable
  • Becomes an astrophotography telescope later without being replaced

What it costs you

  • Expensive per millimetre of aperture. A 200 mm Dobsonian costs less and gathers seven times the light
  • Visually modest on deep sky — this is not what you buy it for

Worth knowing about this model

The current version of the 72ED, with a better focuser. Sharp, portable, colour-free — and a tube only, so budget another 200–400 € for something to put it on. A first astrophoto lens more than a first telescope.
