Vaonis Vespera 3

6.9/10 research score Apochromatic refractor

List price $2,490 (as of Oct 2026)

Best for: All-night sessions with minimal fuss and a long warranty

Our verdict

A beautifully engineered, low-fuss telescope with the longest battery life and warranty in its class. But its imaging hardware (50 mm aperture, IMX585 sensor) is close to the $999 Seestar S50 Pro, light-pollution and solar filters cost extra, and independent hands-on tests are still scarce. Buy it for build, battery and warranty, not for more image per dollar.

Vaonis makes the most design-led smart telescopes on the market, and the Vespera 3 (April 2026) is its new mid-range model. It keeps the Vespera's 50 mm aperture and metal chassis, adds a redesigned apochromatic quadruplet with a stray-light baffle, matches the Vespera Pro's 11-hour battery and comes with a 5-year warranty. At $2,490 it is also two and a half times the price of the Seestar S50 Pro. We compared Vaonis's published specs with the little hands-on coverage available so far. We have not tested it ourselves; see how we research.

Specs from Vaonis's product pages, checked October 17, 2026. Vaonis's store showed us euro prices; US list prices reported by other reviewers are the same figures in dollars.

What's new

According to Vaonis, the Vespera 3 and Pro 2 share a new "three-group, flat-field apochromatic quadruplet" for finer stars and better blue and red sensitivity, and "a new optical baffle that significantly reduces the halos caused by stray light", which helps near streetlights but does not remove general skyglow. Storage rose to 115 GB at the request of Vespera II owners, front-lens defogging is standard, a tall aluminum tripod is now included, and the warranty went to five years.

Image quality

The Vespera 3 uses the same 1/1.2-inch Sony IMX585 sensor as the Seestar S30 Pro and Vespera II, behind 50 mm of high-quality glass. Its native 2.5° × 1.4° field suits large nebulae; the CovalENS mosaic mode stitches frames up to 24 MP for targets like the Andromeda Galaxy. The single owner review we found, published by Zelpio, found the default processing "favors high contrast", which can hide faint nebulosity until you lower contrast in the app's Sky Color tool or process the 16-bit FITS files on a computer.

Battery, storage and automation

Eleven hours on one charge is the standout practical feature: the same as the Vespera Pro 2 and two hours more than the Seestar S50 Pro's 9-hour rating. The Zelpio review reported about 12 hours in real use. Plans can run all night, with up to 15 multi-night slots for adding data over several nights.

What it lacks

  • Built-in filters: filters screw on by hand, so an all-night plan mixing nebulae and galaxies needs you to swap them (Zelpio). The dual-band filter costs extra, about $400; the Zelpio reviewer called it overpriced.
  • Solar filter: sold separately.
  • Wide-angle camera: none, unlike most cheaper rivals.
  • Automatic dark frames: Zelpio saw hot pixels as green rows, which it attributes to the lack of automatic dark calibration.
  • Software quirks: Zelpio found the capacitive power button takes practice and repeated plans can create duplicate multi-night observations.

Value

This is the hard part. The Vespera 3's optics and sensor are close to the Seestar S50 Pro (50 mm, 1/1.2-inch 8.3 MP sensor), which costs $999, includes a dual-band filter, a solar filter and a wide-angle camera, and weighs 6.2 lb instead of 11 lb. What the Vespera 3 adds is build quality, the 11-hour battery, automatic anti-fog, a 5-year warranty and Vaonis's 30-day trial.

Who should buy it

  • Buy it if you value a polished, low-maintenance instrument with all-night battery and a long warranty, and the price is not the deciding factor.
  • Choose the Vespera Pro 2 if you want finer detail on small galaxies.
  • Choose the Seestar S50 Pro if you want similar image hardware, built-in filters and a wide-angle camera for $1,500 less.

How the Vaonis Vespera 3 scores

6.9/10 Fair research score
Image quality
7.0
50 mm apochromatic quadruplet with a field corrector and a 1/1.2-inch 8.3 MP sensor; up to 24 MP mosaics.
Versatility
6.0
Strong on nebulae and galaxies; 245 mm is short for planets and solar and dual-band filters cost extra.
Ease of use
9.0
Self-orienting setup, automatic everything and an AI guide (LumENS) in the Singularity app.
Portability
7.0
11 lb, but an 11-hour battery means no power bank.
Features
6.0
Anti-fog, 115 GB, FITS and TIFF output, multi-night slots; no built-in light-pollution filter or wide-angle camera.
Reliability
8.0
5-year warranty, the longest among mainstream smart telescopes; launched in 2026.
Value
5.0
$2,490 for 50 mm optics; Seestar and Dwarflab offer similar aperture for far less.

Frequently asked questions

What is the difference between the Vespera 3 and the Vespera Pro 2?

The Pro 2 has a square 12.5 MP Sony IMX676 sensor (vs the Vespera 3's 8.3 MP IMX585), finer 1.6 arcsec/pixel sampling, 225 GB instead of 115 GB, mosaics up to 50 MP and a carbon-fiber tripod. Both have the same 50 mm, 245 mm optics, 11-hour battery and 5-year warranty. The Pro 2 costs $500 more.

Does the Vespera 3 have a light-pollution filter built in?

No. Vespera filters screw on by hand. Vaonis currently adds its City Light Suppression filter and a backpack free with the Vespera 3; the dual-band filter is sold separately.

How long does the Vespera 3 battery last?

Vaonis rates it at 11 hours. One owner review on Zelpio reported about 12 hours in real use.

Can the Vespera 3 photograph planets?

Not in detail. Its 245 mm focal length shows planets as small discs; Vaonis designs the Vespera range for nebulae, galaxies and clusters.

Unistellar Odyssey Pro Review: Easy, With an Eyepiece, Priced High

Unistellar's Odyssey Pro adds a Nikon-developed electronic eyepiece to the 85 mm Odyssey. We compare its published specs with what Sky at Night Magazine, Popular Science and other hands-on reviewers found, and ask whether the eyepiece is worth $2,000.

Seestar vs Vaonis Vespera: Is a $2,490 Vespera Worth It?

ZWO's Seestar S50 Pro and Vaonis's Vespera 3 and Pro 2 all use 50 mm apochromats and similar sensors. What the extra $1,500 to $2,000 buys you with a Vespera, and what the Seestar does better.
