The telescopes
Which smart telescope to choose in 2026
Eleven devices, from 200 to 5,300 euros. The table sets the ten that can be compared side by side. Three lines really decide: the aperture, a dual-band filter, and the price.

The eleven devices, list price included
Every device with its photograph, its price and what it does well. Prices recorded in 2026, excluding promotions and accessories.
Three of the ten devices compared have been used to make my images. The other seven are documented from the manufacturer datasheets and from published reviews. Never from a personal trial, and that is written on every entry.

Is it for you
Who it is for, and what it is not
Before comparing the ten devices in the table line by line, the question no datasheet settles.
Who is it for? For anyone who wants to photograph nebulae, galaxies and star clusters without spending a winter learning how. A conventional telescope asks for three things. Aligning the mount on the pole star. Adding a second device to correct the tracking. Then assembling the images on a computer. Here the device does all three, and the first night already gives you something. That holds under the light pollution of a town as well. It is the case for most of the images published here.
What it is not: an instrument for looking through with your eye, nor a shortcut to the perfect image. Time is still the price to pay. I built this site around that price: the 165h of exposure that produced the 41 entries in the catalogue. They are published image by image, with their duration.
The comparison
The same devices, line by line
Nine columns of published specifications, and their sources. This table ranks nothing and rates nothing.
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.

Two of these devices also exist in an eyepiece version, under another name and at another price: eQuinox 2 becomes the eVscope 2 at ≈ 4 699 €, Odyssey becomes the Odyssey Pro at ≈ 4 199 €. This eyepiece does not open onto the sky: it is a micro screen looked at through a block of lenses, and the image comes from the same sensor. The table compares only the versions without an eyepiece; each entry says what the other one changes and what it costs.
not in the comparison Vaonis Hestia, ≈ €200 in the Essentiel pack, has no line in this table, and its entry 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 each one frames
The full Moon as a reference
A focal length does not say what you will see in the frame. Two devices of the same focal length, with different sensors, do not frame the same portion of sky. So here is the field that each manufacturer publishes, drawn to the same scale, with the disc of the full Moon at the centre. The devices whose manufacturer does not publish a field as width and height keep their thumbnail, and it is empty.
Fields of view published by the manufacturers, all drawn to the same scale, with the disc of la pleine Lune, 0.5°, as the reference. Unistellar eQuinox 2: 34,2′ × 45,6′. Unistellar Odyssey: 33,6′ × 45′. Vaonis Vespera 3: 2,5° × 1,4°. Vaonis Vespera Pro 2: 1,6° × 1,6°. Celestron Origin: 1,32° × 0,75°. Not drawn, for want of a field published as width and height: DwarfLab DWARF 3, DwarfLab DWARF Mini, DwarfLab Draco, ZWO Seestar S30 Pro, ZWO Seestar S50 Pro.

Vaonis publie 2,5° × 1,4° dans son tableau comparatif et 2,6° × 1,4° sur sa page de gamme. Le tableau fait foi ici.
-
1,6° × 1,6°
Vaonis publie deux mosaïques qui se contredisent : 4,18° × 2,45° dans son tableau comparatif, 3,2° × 3,2° sur sa page de gamme. Le tableau fait foi ici.
-
1,32° × 0,75°
Celestron publie ce champ pour la Mark II, celle dont le prix est relevé ici.
-
not drawn 3°
DwarfLab publie deux valeurs qui ne concordent pas : « 3° » en présentation, et « D : 3,38° au téléobjectif » dans son tableau de caractéristiques, où la lettre D dit que c'est une diagonale. Le nombre de la présentation est repris ici ; aucun des deux n'est une largeur et une hauteur, donc aucun ne se dessine.
-
not drawn 2,45°
DwarfLab publie une diagonale, et il le dit : son tableau de caractéristiques écrit « D : 2,45° au téléobjectif » et « D : 50,59° au grand angle ». Une diagonale seule ne donne ni la largeur ni la hauteur du cadre : la vignette reste vide.
-
not drawn 2,059° en diagonale au téléobjectif, en mode astronomie
DwarfLab ne publie qu'une diagonale, précédée de la lettre D, jamais une largeur et une hauteur. Il publie aussi 1,936° dans les autres modes, et 85,74° en diagonale au grand angle.
-
not drawn 4,6° au téléobjectif
ZWO publie un seul nombre, sans dire s'il s'agit de la largeur, de la hauteur ou de la diagonale. Il publie de même 63° au grand angle.
-
not drawn 2,8° au téléobjectif, en cadrage portrait
ZWO publie un seul nombre, sans dire s'il s'agit de la largeur, de la hauteur ou de la diagonale. Il publie de même 63° au grand angle.
The disc at the centre of each thumbnail is la pleine Lune, 0.5°, the value the glossary already publishes. The 5 frames drawn are at the same scale, a square 2.7° on a side: they are really being compared, instead of each being looked at in its own box.
None of these fields is calculated. Each one is copied from the manufacturer page, recorded on 14/09/2026. The only operation applied is the conversion of arcminutes into degrees, at 60′ to 1°. A field cannot be worked out from the focal length or from the focal ratio: the sensor size is needed, and the resolution a manufacturer publishes is not always that of its sensor. Not all manufacturers say which side is the width: the longer published side is drawn horizontally.
The Vaonis Vespera 3 also publishes a en mosaïque CovalENS field of 4,33° × 2,43°, too large for this shared frame: it is not drawn here. The Vaonis Vespera Pro 2 also publishes a en mosaïque CovalENS field of 4,18° × 2,45°, too large for this shared frame: it is not drawn here.
What is missing is written down. 5 of the 10 devices compared have no frame: their manufacturers do not publish a field as width and height. The figures they do publish are repeated as they stand under the thumbnails. I do not fill in the rest from memory.

Which one for you
Four situations, four answers
Each route states its criterion first. It is the criterion that picks the device. The lowest price, the highest resolution, the largest aperture, or the time spent with it. No route says “best”, and each one carries what works against it.
-
01
The smallest budget, and you leave with it.
the lowest price in the panel
≈ €429 · 30 mm of aperture · f/5 · 0,84 kg
In this panel: the lowest price, the lowest weight.
I have never had it in my hands. Its scale stays at zero and its gallery stays empty. Its entry is built on public sources.
-
02
Less than 600 euros, and you want nebulae from the very first night.
under 600 euros, the one I have really worked with
≈ €529 · 35 mm of aperture · f/4,3 · 1,3 kg
Under 600 euros: the largest aperture, the highest published resolution, the fastest focal ratio.
Recorded first hand: 34 shots, 23 objects, 98h 04m logged with it in this catalogue.
-
03
Budget is not the constraint, and you want optics rather than diameter.
the highest published resolution in the panel
≈ €2,990 · 50 mm of aperture · f/4,9 · 5 kg
In this panel: the highest published resolution.
Recorded first hand: 5 shots, 4 objects, 62h 37m logged with it in this catalogue.
-
04
Fixed post in the garden, large diameter, short evenings.
the largest aperture in the panel
≈ €5,300 · 152 mm of aperture · f/2,2 · 19 kg
In this panel: the largest aperture, the fastest focal ratio.
I have never had it in my hands. Its scale stays at zero and its gallery stays empty. Its entry is built on public sources.
These four routes read published specifications and hours actually logged. They do not rank the devices and do not rate their quality. An empty track is a device that was not tested, not a bad device.
None of the four looks like you? Say your budget and what you want to photograph: the answer will say which of the eleven suits, and which does not.
A device is missing
The market moves fast
A model released, a price that changes, a specification that is wrong: report it, and it will be corrected and dated.
