Vaonis Vespera II Smart Telescope

A fully automated smart telescope: it finds, tracks and stacks deep-sky targets and builds the image live on your phone. No eyepiece, no mount, no learning curve, point the app and watch nebulae appear.

What it's built forOpen these in the simulator →

This telescope was built to capture, not to squint.

Point it, tap a target, and it stacks a live image on your phone — color and faint detail no eyepiece will show you. The trade is simple: the experience lives on a screen, not at an eyepiece.

The view people remember

The Orion Nebula, wings unfolded.

The four stars of the Trapezium sit inside folded sheets of glowing gas — the closest stellar nursery to us, bright enough to show real structure even from the suburbs.

01What it's good at

What it's best at — and the trade-offs.

Completely automated: it plate-solves, points, tracks and live-stacks, you just pick a target in the app.
Best at
✓Completely automated: it plate-solves, points, tracks and live-stacks, you just pick a target in the app.
✓A 50mm apo and Sony sensor pull faint nebulae and galaxies out of light-polluted skies in minutes.
✓Sets up in under a minute, runs off its own battery, and needs no eyepiece or separate mount.
✓Multiple people can watch the image build live on their own phones.
Trade-offs
!No eyepiece and no manual control, the app runs the whole session.
!Small 50mm aperture and short focal length suit wide nebulae, not small or planetary targets.
!Results depend on the app and Vaonis servers; it is a closed ecosystem.
!Upgrade path is limited, it is a sealed, self-contained instrument.
02In plain English

What These Numbers Mean

50mm · f/5 · 250mm FL · Integrated Alt-Az GoTo
Aperture
50 mm
Two inches of aperture, so results come from stacking many frames rather than raw light grasp. Large bright nebulae, clusters and the Andromeda Galaxy work well; small faint targets are beyond it.
Focal length
250 mm
A wide field that suits exactly the large showpiece objects most people want their first images of. Its mosaic mode stitches several frames to cover even wider areas.
Focal ratio
f/5
Fast enough that ten-second frames carry usable signal, which is what allows a recognisable image to appear within a few minutes of selecting a target.
Optical design
Sealed smart refractor with built-in camera
A four-element apochromatic lens with a fixed camera behind it and no eyepiece. The whole experience is on a phone or tablet, and several people can follow the same session at once.
Weight
5 kg complete
About 11 lb including the integrated mount. It fits in the supplied bag and sets up on any flat surface, which is central to how this class of telescope is meant to be used.
Mount
Integrated alt-azimuth GoTo
The telescope levels itself, plate-solves the sky and finds targets automatically, then tracks them while stacking. There is no alignment routine and nothing to focus.

Polaris weighs optical capability, how easy the scope is to live with, how portable it is, and how far it takes you before you outgrow it — not list price or brand.

04Who it's for

An honest fit check.

Beginners and families who want deep-sky images without the learning curve.
Buy it if you
✓Beginners and families who want deep-sky images without the learning curve.
✓City observers whose skies defeat a traditional visual scope.
✓People who value convenience and shareable results over hands-on control.
Look elsewhere if you
!Visual observers, there is no eyepiece; it is a screen experience.
!Hands-on imagers who want full manual control of the capture and processing.
!Anyone wanting planetary detail; the short focal length is built for wide deep-sky fields.
