- Unistellar doesn't publish the sensor model; BBC Sky at Night names the Sony IMX415 for the Odyssey Pro, which shares these optics.
- Output resolution is reported inconsistently: 3.4 MP in Digital Camera World's Odyssey review, 4.1 MP in Space.com's and DCW's Pro coverage.
- Digital Camera World's spec table gives f/3.8; Unistellar says f/3.9.
Specs are compiled from manufacturer pages, Amazon listings and independent reviews, and may change with firmware or production runs. Confirm what's in the box (tripod, solar filter, case) on the Amazon page before buying.
Unistellar Odyssey Smart Telescope video review
Video by Anthony Robinson | Skies & Scopes on YouTube. Independent creator content, shown as a reference. It is not part of our scoring.
The Unistellar Odyssey is the simplest scope in Unistellar’s range: an 85 mm Newtonian with autofocus, no collimation and a free app that walks you from target to target. It costs about $2,079 on Amazon (Nov 12, 2026), sold and shipped by Amazon against a $2,599 list price, so check today’s price before you buy. We haven’t tested it ourselves; this review pulls together what named outlets found and what Unistellar claims.
Who it’s for (and who should skip it)
The Odyssey suits families, schools and outreach observers who want to share live views of galaxies and clusters on phones and tablets without learning any astronomy software. The citizen-science side is a genuine draw: the app runs NASA and SETI campaigns, so a backyard session can feed real observations.
Skip it if you want big, wide nebula pictures. Its field is only 45 × 33.6 arcminutes (Unistellar figure), there’s no mosaic mode, and there’s no physical light-pollution filter. A Seestar S50 Pro frames far more sky with a built-in dual-band filter for about half the price. Skip it too if planets are the priority: Space.com calls the Odyssey line not ideal for planetary work.
Imaging in practice
Unistellar rates the Odyssey to limiting magnitude 17.2, and its 0.93″ sampling is fine for a smart scope, which is why it suits small, bright targets: the Ring Nebula, the Whirlpool Galaxy, the Hercules Cluster. On Jupiter, our tool math gives a disc of roughly 48 pixels, bigger than any 30–50 mm smart scope manages, but output resolution is modest. Digital Camera World’s Odyssey review gives 3.4 MP, while Space.com and DCW’s Odyssey Pro coverage quote 4.1 MP for the same optics.
Digital Camera World rated the Odyssey 4 out of 5. Its one practical gripe: the battery only recharges with the supplied adapter cable, so don’t lose it. Unistellar quotes up to 5 hours per charge.
The narrow field is the real constraint. Large targets such as the Andromeda Galaxy or the North America Nebula simply overflow the frame. Check how your favorite objects fit with the FOV calculator, and see what’s well placed tonight from a suburban sky with the sky target checker.
App and workflow
Setup is the Odyssey’s strength. With autofocus and no collimation, you level the tripod, power on, connect your phone and pick a target from a catalog of 5,000+ objects. The scope finds its position, slews and starts stacking, and the image builds up on screen as more light arrives. Light pollution is handled in software (Unistellar calls it Deep Dark Technology) rather than with a filter.
The mount is alt-az only with no EQ mode, so field rotation is handled in software. Unistellar lists a 2-year warranty.
What you’ll need beyond the box
- Solar filter. Unistellar’s Smart Solar Filter is sold separately (about $199 per Digital Camera World). Use only the maker’s filter on this scope. For your own eyes during the session, a pair of ISO 12312-2 eclipse glasses is cheap insurance; never look through any telescope with them.
- A case. The Unistellar Odyssey backpack is airline cabin size and holds the scope and tripod.
- Phone power. The app runs on your phone all night. A UGREEN 20,000 mAh power bank keeps it topped up; the telescope itself charges only from its own cable.
- A red light. A dimmable red flashlight helps you find cables and the tripod without ruining your night vision.

How it compares
The Odyssey Pro is the same scope with a Nikon eyepiece for about $1,600 more. The eQuinox 2 costs a little more and offers 114 mm of aperture and an 11-hour battery (maker figure), but you focus and collimate it yourself. The Seestar S50 Pro is the value choice for wide fields. Our Seestar vs Vespera vs Unistellar comparison lays out the trade-offs, and the beginner’s guide covers cheaper starting points.
Bottom line
The Odyssey is Unistellar’s most approachable telescope and a strong pick for groups, families and citizen science. It’s a small-target instrument at a big-target price, so buy it for the shared experience and the science program rather than for the widest, most colorful pictures. If that matches what you want, check the price on Amazon.

Adjustable ISO 12312-2 compliant film filter for objectives with an outside diameter of 75–100 mm, such as spotting scopes and some traditional telescopes. Too big for 30–50 mm smart scopes; use the maker's own solar filter on those.
- SolarThousand Oaks black-polymer solar filter sheet, 4 × 4 inUniversal fit
DIY solar film for making a secure full-aperture filter cell for a small scope or camera lens. Only for confident DIYers: the cell must fit tightly over the front so it can't blow off. Never use a filter at the eyepiece end.
