The Vaonis smart telescopes

The most worked optics at small diameter. And the most accomplished mosaic: several fields assembled into one image.

Official site

A manufacturer based in Montpellier. It is the most carefully finished of the five, in the design of the object as much as in the optics. The Vespera Pro 2 carries a 50 mm four element lens. That is called an apochromatic quadruplet. Its glass scatters colours very little: no coloured fringe around the stars. Vaonis aims at image quality rather than diameter.

The range

Two devices in the comparison

Rapport d'ouverture : the focal length divided by the diameter, written f/, and the smaller that number, the faster the image forms. Monture azimutale : it moves in altitude and in rotation, but the field turns during the night.

f/4.9 · Sony IMX585, format 1/1.2 inch, 11.2 × 6.3 mm, 2.9 µm photosites

Vespera 3

A 50 mm apochromatic quadruplet with a flat field, with baffling against stray light. Large 2.9 µm photosites: it is quick, where the Pro 2 is fine.

Vespera Pro 2

Same optics as the Vespera 3, square 12.5 Mpx sensor with small photosites. Mosaics up to 50 Mpx: the highest final resolution of the devices compared here.

This equivalence says nothing about resolution, about the field or about optical quality: f/2,2 on 152 mm and f/5,3 on 30 mm do not photograph the same objects. Worked out from the published focal ratios alone, with sensor, sky and target held identical.

not in the comparison Vaonis Hestia, ≈ €200 in the Essentiel pack, is not in this range and has no line in the comparison. Its entry exists, and it says why: This is not a smart telescope. Six lenses, 30 mm, no motor, no tracking, no sensor. The image forms in the camera of the phone you set on top of it. The comparison table has the sensor, the mount and the focal ratio for its columns. Filing the Hestia there would blur the category instead of lighting it up. So it has its entry, and it has no line.

What these devices really produce

No manufacturer image, no stock image. Each thumbnail keeps the aspect ratio of its sensor: the shape of the frame says which instrument the photograph was made with.

Following this brand

What is checked, and what is not

This page does not copy out a press release. Here is how it is made, and what it does not claim to know.

  • The specifications come from the manufacturer datasheets and from published reviews, listed on each product entry.
  • Prices are recorded in 2026, excluding promotions, and they move fast: they are indicative.
  • At least one device from this brand has been used to make the images published here: my notes on using it come from practice.
  • The scale above measures the hours ofintegration (the total exposure time, the sum of every exposure stacked on an object) logged with these devices, from 0 to 165h across the whole catalogue. It is not a quality rating: an empty track is a device that was not tested, not a bad device.
  • The devices from this brand can be ordered from me, and I earn an income from them. No brand funds these pages. No link earns a commission. No manufacturer proofreads what I write here. That is why this page also publishes the weak points, and says which devices I have never tried.
