Unistellar eQuinox 2 Smart Telescope video review
Video by Tech Guide on YouTube. Independent creator content, shown as a reference. It is not part of our scoring.
The Unistellar eQuinox 2 is the biggest aperture you can get in a fully automatic smart telescope at its price: a 114 mm Newtonian feeding a 6.2 MP output, with an 11-hour battery by Unistellar’s figure. It costs about $2,319 on Amazon (Nov 12, 2026), sold and shipped by Amazon, against a $2,899 list; Unistellar showed the same Black Friday price. Check today’s price. We haven’t tested it ourselves; this review draws on BBC Sky at Night, Space.com, Universe Today and Unistellar’s specs.
Who it’s for (and who should skip it)
It’s for backyard observers who want the most light-gathering per dollar in an automatic scope, mainly for small, faint galaxies and deep views shared on a tablet. Space.com’s 2026 roundup names it the best smart telescope overall.
Skip it if you want wide nebula portraits, a built-in light-pollution filter or a grab-and-go scope. The field is narrow, there’s no mosaic mode and no physical filter, and the scope weighs 15.4 lb plus a 4.4 lb tripod (Amazon listing). A Seestar S50 Pro frames wide nebulae with a dual-band filter for less than half the price.
Imaging in practice
BBC Sky at Night (Jamie Carter) rated the eQuinox 2 4.5 out of 5, while finding its images “a little soft”. Universe Today reported that the eQuinox 2 moved from the original eQuinox’s IMX224 sensor to the IMX347, which is where the higher 6.2 MP output comes from.
Unistellar rates it to limiting magnitude 18.2, a magnitude deeper than the 85 mm Odyssey’s 17.2, at 1.33″ sampling. That makes small galaxies such as M51 and M81, and globular clusters, its natural targets. On Jupiter, our tool math gives a disc of roughly 34 pixels, larger than small smart scopes manage, though Unistellar scopes aren’t planetary specialists.
The 45.6 × 34.2 arcminute field is the limit. The Andromeda Galaxy (about 3° long) would need roughly a 5 × 3 grid. Plan targets with the FOV calculator, estimate stacking time with the integration time tool, and see what’s visible tonight with the sky target checker.
App and workflow
The free Unistellar app (iOS and Android) handles alignment, target selection and live stacking, with software light-pollution reduction (Deep Dark Technology). It also runs NASA and SETI citizen-science campaigns. We found no subscription or in-app purchases.
The eQuinox 2 is more hands-on than the Odyssey. You focus manually using the Bahtinov-mask cap and collimate the mirror yourself from time to time. Neither is hard with the app’s guidance, but it’s the oldest design here and feels it. The mount is alt-az only, with no EQ mode. BBC Sky at Night found that third-party USB-C cables didn’t charge it, so treat the supplied cable as essential. Unistellar lists a 2-year warranty.
What you’ll need beyond the box
- Solar filter. Unistellar’s Smart Solar Filter for eVscope 2 and eQuinox 2 is sold separately. Use only that filter on this scope, and wear ISO 12312-2 eclipse glasses for naked-eye viewing, never at the telescope.
- A backpack. At 15.4 lb the tube needs protection in the car. The Unistellar backpack for eVscope 2 and eQuinox 2 is form-fitted with internal straps and a rain cover.
- Phone or tablet power. The scope has its own battery, but your phone runs the app all night. A UGREEN 20,000 mAh power bank covers it.
- A red light. A red LED flashlight for collimation and cables in the dark.

How it compares
The Odyssey costs a little less, skips focusing and collimation, and has a slightly smaller 85 mm mirror. The eVscope 2 is this telescope plus a Nikon eyepiece and 7.7 MP output for about $1,700 more. Our best smart telescopes of 2026 roundup and the Seestar vs Vespera vs Unistellar comparison show where it sits against wide-field rivals.
Bottom line
The eQuinox 2 gives you the most aperture in an automatic smart scope for the money, a long battery and a free science program. Accept manual focus, collimation, a narrow field and slightly soft images per BBC Sky at Night, and it’s an excellent small-galaxy machine. Check the price on Amazon.

- CaseUnistellar transportation backpack for eVscope 2 and eQuinox 2Official Unistellar
Form-fitted backpack with internal straps and a rain cover for Unistellar's 114 mm scopes.
- SolarCelestron EclipSmart universal solar filter (75–100 mm)Universal fit
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.
- SolarSoluna ISO 12312-2 solar eclipse glasses (2-pack)Universal fit
For looking at the Sun with your own eyes while the scope images it; never look through a telescope with them.
- PowerAnker 737 power bank, 24,000 mAh, 140 WUniversal fit
USB-C PD power bank big enough to run a 30–50 mm smart scope through a long winter night, when cold cuts battery life. Check your scope's manual for supported USB-C input while observing; Unistellar, Vaonis and Celestron Origin use their own batteries and chargers.
- PowerUGREEN Nexode 100 W power bank, 20,000 mAhUniversal fit
Cheaper USB-C PD bank that also tops up your phone, which runs the telescope's app all night.
