No eyepiece at all — a sensor, a phone and a stack · review
A self-contained imaging telescope with a Sony IMX676 sensor, an apochromatic flat-field quadruplet objective and an app that stacks exposures across several nights automatically.
The bottom line The most completely specified instrument on this shelf, and the one furthest from the traditional idea of a telescope.
Vaonis publishes the figure that matters for this kind of device: 1.6 arcseconds per pixel, with a Sony IMX676 behind an apochromatic flat-field quadruplet. That single number says more about what the system can resolve than any aperture-and-focal-length pair would, because sensor and optics are fixed to each other here.
Manual exposures from one to thirty seconds, gain from zero to thirty decibels, automatic dark calibration, and stacking that continues across nights. The output is FITS or TIFF — the formats that Pixinsight and Siril read — so the data is not trapped inside the app.
Eleven hours of battery, 225 GB of storage, an aluminium tripod and a hard case in the box, a five-year warranty and French manufacture. Those are the figures that decide whether an instrument like this is usable on a trip, and all of them are published.
It is not a visual telescope, and its pixel scale is coarse for planetary work. It is built for wide, faint, slow targets — and for producing an image while the owner is indoors.
German, French, Italian and Spanish Amazon stores ran from 2990 € to 3089 € on the day of the survey.
American and British Amazon stores list it in local currency, which the euro range above sets aside.

No. The output is an image on a phone or tablet and files on internal storage. That is the design, and it is why the arcsecond-per-pixel figure matters more here than any eyepiece specification would.
Signal accumulates with total exposure time regardless of which night it came from. Automating the re-acquisition across nights is what makes tens of hours practical on a single target.
Automatic alignment accessory · four-element optics
An accessory that bolts to a computerised Celestron mount and aligns it on the sky automatically in about three minutes, then improves its pointing and assists polar alignment.
Best for: An owner of a computerised Celestron mount who is tired of three-star alignments
≈ $827 / £652 / €792
80 mm aperture · 400 mm focal length · Bluetooth PushTo
An 80/400 refractor whose built-in sensors report where it is pointing to a free phone app, which then guides the observer to a target with on-screen arrows.
Best for: A beginner who wants help finding objects without the cost or weight of a GoTo mount
≈ €259
8 MP sensor · 1.25 in eyepiece fitting · M28.5 × 0.6
An 8 MP electronic eyepiece camera that replaces the eyepiece in a 1.25 in focuser and streams live video to a computer over USB, with an IR-cut filter fitted.
Best for: Lunar and planetary video, and showing a live view to more than one person at once
≈ $80 / €96
