Still unsure whether it should be a Unistellar at all? The smart telescope finder takes you from your budget to the right class of device in three questions.

Unistellar Odyssey: specifications, price and what’s in the box

The Odyssey and Odyssey Pro have the same optics, the same sensor and the same mount. The only difference is the Pro’s electronic eyepiece. All figures below come from Unistellar (as of 30/09/2026), the tripod weight from the Unistellar shop.

How the Odyssey works: “Enhanced Vision” explained

The Odyssey has no glass eyepiece through which light reaches your eye directly. Inside the reflector sits a camera that takes a short exposure every few seconds. Unistellar calls the result “Enhanced Vision”.

Every other manufacturer calls the principle live stacking: the individual frames are continuously stacked on top of each other, the noise averages out and the object becomes brighter and more detailed with every minute. Seestar, DWARF and Vaonis do exactly the same – it isn’t new.

What really makes the Odyssey special is its long focal length combined with very small pixels. At 0.93″ per pixel, it images about two and a half times more finely than the Seestar S50 Pro (2.3″ per pixel). Small objects therefore appear large, while large ones no longer fit in the frame.

The app does the rest: the Odyssey works out where it’s pointing from the stars (plate solving), focuses automatically and uses the “Smart Star Finder” to suggest objects that are well placed right now. Against city light, “Deep Dark Technology” subtracts the brightened background.

Unistellar Odyssey Pro: is the eyepiece worth it?

The Pro’s eyepiece is a small OLED display behind Nikon optics. You look into it as you would with a normal telescope and see the same stacked image that the app shows. The Pro costs about $4,199€ 4.199 instead of about $2,399€ 2.399 – the entire extra cost goes into this eyepiece.

Pro owners often rave about the eyepiece. One owner on Reddit describes the Orion Nebula looking more three-dimensional in the eyepiece than on the iPad, and one owner on Cloudy Nights calls it “magical” for showing the sky to others. BBC Sky at Night and Skies & Scopes praise it as well.

But it remains a screen, not a view through the optics. The PetaPixel reviewer found the experience lovely but couldn’t justify the extra cost. And for the first few seconds the image in the eyepiece is dark until enough frames have been stacked – Sky at Night points this out too.

Our assessment: for most people, the Odyssey without the eyepiece is the more sensible choice. If you really want the eyepiece, weigh the Pro against the eVscope 2*eVscope 2* ($4,999.00€ 4,911) – it also has a Nikon eyepiece, but more aperture. Unistellar offers a red special edition of the Pro at a higher price; technically it’s identical.

With electronic Nikon eyepiece: Unistellar Odyssey Pro Smart Telescope

Identical in construction to the Odyssey, plus an electronic eyepiece for that classic telescope feeling. Mainly worthwhile if you often observe together with others.

What you see with the Odyssey – and what doesn’t fit in the frame

At 45 × 33.6 arcminutes, the Odyssey’s field of view is very small. That’s just about the height of the full Moon. The Seestar S50 Pro shows eight times as much sky, and the DWARF 3 a good eleven times as much.

Small objects are the Odyssey’s strength, large ones its weakness. Anything smaller than about half the Moon’s width fills the frame nicely. Anything extended only works as a crop.

Object sizes rounded from common catalogue values.

Planets: Jupiter comes out at just under 50 pixels

Unistellar advertises Jupiter’s Great Red Spot and Saturn’s rings – and that’s accurate. At 0.93″ per pixel, Jupiter (around 45″ near opposition) comes out at just under 50 pixels, more than twice as large as in the Seestar S50 Pro. Saturn’s ring system reaches a good 40 pixels in width.

For planet fans, it’s still the wrong choice. All the expert reviews and the buyer review at Astroshop say that planets can’t keep up with classic telescopes; in our own review of the eVscope 2, too, Jupiter and Saturn were overexposed and lacking in detail. A classic 150 mm telescope with a planetary camera costs a fraction of the price and shows considerably more.

Moon and Sun

The Moon almost always fits completely in the frame, though the edge gets tight when it’s very close to Earth. The resolution is good for close-ups of individual craters.

Odyssey vs. Seestar S50 Pro, DWARF 3 and eVscope 2

In terms of price, the Odyssey plays in a different league from the bestsellers by ZWO and DWARFLAB. The table shows what you get for the extra money – and what you don’t.

Odyssey or Seestar S50 Pro?

On paper, the 85 mm mirror collects almost three times as much light as the Seestar’s 50 mm lens. Some of that is lost because the camera sits in the middle of the light path; Unistellar doesn’t say how much. On small, faint galaxies, that gives the Odyssey the edge.

The Seestar, in turn, wins on anything extended: Andromeda, the Pleiades, the North America and Heart Nebulae, plus narrowband filters for nebulae from the city, a mosaic mode and twice the battery life. For most beginners it’s the more versatile device – for a fraction of the price.

The Odyssey is only worth it over the Seestar if you have a clear reason: you mainly want to see small galaxies and globular clusters large, take part in citizen science campaigns or – with the Pro – have an eyepiece. Everything about the Seestar is in our Seestar S50 Pro check.

💶 The honest cheaper alternative: Seestar S50 Pro

The Seestar S50 Pro shows eight times as much sky and has filters, a mosaic mode and nine hours of battery. On small galaxies it delivers smaller images, but on large nebulae it’s clearly superior. If you don’t specifically need the Odyssey’s strengths, you’ll save a lot of money here.

Best value for money: ZWO Seestar S50 Pro Smart Telescope

50 mm apochromat, dual-band filter, mosaic mode and up to 9 hours of battery – the more versatile smart telescope for most beginners.

Odyssey or eVscope 2 and Equinox 2?

Within Unistellar’s range, the Odyssey is the compact model, while the “Expert” line with the eVscope 2 and Equinox 2 is the larger one. Both have 114 mm of aperture and 450 mm focal length – yet the field of view is almost the same size because a different sensor is fitted.

The larger aperture adds a full magnitude: Unistellar quotes a limiting magnitude of 18.2 mag for the eVscope 2 instead of 17.2 – stars and galaxy cores that are two and a half times fainter. In return, it weighs 9 kg with the tripod instead of 6.5 kg.

The Equinox 2 is the underrated option: 114 mm, eleven hours of battery, 7 kg, but no eyepiece. In the Unistellar shop on 30/09/2026 it cost less than a tenth more than the Odyssey (about $2,399€ 2.399) – if you don’t mind the size, you get more aperture for your money there.

🔭 If you want more: Unistellar eVscope 2

The eVscope 2 has 114 instead of 85 mm of aperture, i.e. around 80 % more light-collecting area, and reaches a magnitude deeper. On top of that come the Nikon eyepiece, as on the Pro, and nine instead of five hours of battery. The extra cost is worth it for anyone who hunts the faintest possible galaxies and comets from a fixed location and doesn’t have to carry the 9 kg far – we tested it ourselves.

For advanced users: more aperture: Unistellar eVscope 2 Smart Telescope

114 mm mirror, limiting magnitude 18.2 mag according to Unistellar, Nikon eyepiece and 9 hours of battery – the next step up from the Odyssey Pro.

Our nights with the device: Unistellar eVscope 2 hands-on review.

Citizen science: observing for SETI and NASA with the Odyssey

The citizen science programme is what sets Unistellar apart from all other smart telescopes. Unistellar runs it together with the SETI Institute in California, and NASA is involved in the exoplanet campaigns. Anyone with a Unistellar telescope and the free app can take part.

This isn’t a marketing gimmick – there are real results. Measurements from the Unistellar network fed into an analysis of NASA’s DART asteroid impact published in Nature. According to Unistellar, 26 citizen scientists tracked the asteroid 1999 AP10, and 40 observed the break-up of Comet ATLAS.

Unistellar Odyssey reviews and experiences: what the trade press and owners report

Transparency: we haven’t had the Odyssey in our own hands. We read five expert reviews and counted all posts by verified owners on Reddit, Cloudy Nights, the German forum astronomie.de and at Astroshop (as of 30/09/2026). The eVscope 2, which uses the same app and the same principle, on the other hand, we tested ourselves over several nights.

What 9 owners report

We only counted people who verifiably own the Odyssey or Odyssey Pro: four owners on Reddit, three on Cloudy Nights and two buyers with reviews at Astroshop – seven with the Pro, two with the Odyssey. On the German forum astronomie.de we only found retailer posts, one sales ad and comments on the launch. The sample is small, so the numbers are trends, not statistics.

The harsh criticism comes almost exclusively from non-owners. On Reddit and Cloudy Nights the words “overpriced” and “bad images” come up often, mostly from Seestar and Vaonis users. The loudest voice is a former eVscope 2 owner who posts in almost every Unistellar thread – that skews the picture.

On the substance, though, the critics have a point: for the money, Seestar or Vaonis give you more features, and owners would like more frequent software updates. If you’re looking for a device for viewing, this bothers you little; if you want to process astrophotos, you’ll hit the limits sooner.

Who the Unistellar Odyssey is worth it for

In short: the Odyssey is a good device with a difficult price. It’s worth it if its particular strengths match exactly what you want.

Frequently asked questions about the Unistellar Odyssey

How much does the Unistellar Odyssey cost?

The Odyssey costs about $2,399€ 2.399, the Odyssey Pro with electronic eyepiece about $4,199€ 4.199. Both are in stock at Astroshop; the prices on this page are updated automatically every day.

What is the difference between the Odyssey and the Odyssey Pro?

Only the eyepiece. Optics, sensor, mount, battery and app are identical. The Pro also has an electronic eyepiece with Nikon optics, in which you see the stacked image as in a classic telescope.

Can you really look through the Odyssey Pro?

You look into an eyepiece, but what you see there is a small display, not direct light from the sky. The image is the same stacked camera image as in the app. It feels like looking through a telescope and many people enjoy it, but it remains a screen.

Which sensor is in the Odyssey?

Unistellar doesn’t name the sensor itself. According to Space.com it’s a Sony IMX415; that matches the stated pixel size of 1.45 µm and the field of view of 45 × 33.6 arcminutes exactly. The eVscope 2 uses a different Sony sensor (IMX347).

Is the Odyssey better than the Seestar S50 Pro?

On small galaxies and globular clusters, yes: more aperture, finer image scale. On large nebulae, Andromeda and the Pleiades, the Seestar S50 Pro*Seestar S50 Pro* with its eight times larger field of view is clearly better – and it costs only a fraction of the price.

Can you see planets with the Odyssey?

Yes, Jupiter with its cloud belts and Saturn with its ring are recognisable; Jupiter comes out at just under 50 pixels. For beautiful planetary images, though, a classic telescope with a planetary camera is considerably better and cheaper.

How long does the battery last?

About five hours according to Unistellar. For long nights, the PetaPixel reviewer recommends a power bank; the eVscope 2 (9 h) and Equinox 2 (11 h) last considerably longer.

Do I need a subscription for the Unistellar app?

No. According to Unistellar, the app for iOS and Android is included free of charge, as is participation in the citizen science campaigns.

Is the Odyssey suitable for beginners?

In terms of operation, yes – owners and reviewers unanimously praise the quick, easy start. In terms of price, it isn’t a typical beginner’s device: if you don’t yet know how deep you’ll get into the hobby, start with a cheaper smart telescope. Our free telescope advice can help you choose.

Verdict: a specialist with an eyepiece option – but not the best value for money

The Unistellar Odyssey is well thought out, quick to set up and strong on small deep-sky objects. With the citizen science programme and the Pro’s eyepiece, it offers two things no other manufacturer has.

Its problem is the price compared with the competition. For most beginners the Seestar S50 Pro is the better choice, and for more depth the eVscope 2 or the Equinox 2. You’ll find all devices at a glance in our smart telescope overview.
