Unistellar eQuinox 2
A 114 mm Newtonian with enhanced vision: a mirror telescope, with no eyepiece. The image builds on the phone, minute after minute.

For the image the l'Origin makes in 1h, it takes 3h 09m here.
This equivalence says nothing but speed. It says nothing about resolution, about the field, or about optical quality. f/2,2 on 152 mm and f/3,9 on 114 mm do not photograph the same objects. The calculation takes nothing but the published focal ratios, with sensor, sky and target held identical.
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.
The version with an eyepiece
It also exists with an eyepiece
Unistellar sells the same device under a second name, the eVscope 2. It is the only difference in the range, and it costs.
- The name of the version
- Unistellar eVscope 2
- Its price
- ≈ 4 699 €
- The difference
- 2,100 € more, that is 81% of the price of the l'eQuinox 2
What that changes. The eyepiece, and two more lines: the output resolution goes from 6.2 to 7.7 Mpx, and the quoted battery life drops from 11h to 9h. The rest of the manufacturer's table is identical: same mirror, same focal length, same field, same mount, same storage.
What this eyepiece is. A block of lenses placed in front of an OLED micro screen, and nothing more. Unistellar describes it itself as “a sophisticated lens assembly with OLED micro-display technology”, reserved for the eVscope 2 and the Odyssey Pro.
The eyepiece does not open onto the sky. It is a micro screen looked at through a block of lenses, and the image it shows comes out of the sensor, exactly like the one on the phone. No device from this brand is watched live through the glass, with or without an eyepiece.
What you pay for is comfort. 2,100 € more to put your eye to the instrument instead of looking at the phone. Not a truer image, not a deeper image: the same image, on a second screen.
Unistellar stands by the positioning of the version without an eyepiece: “It's an excellent choice if eyepiece observation is not a priority for you.”
Ask for a price for the eVscope 2 version. It has no entry here, and it does not go into the comparison: the table compares only the versions without an eyepiece.
The device
Seen from closer up
The other images published by Unistellar for this device.
Where it excels
What it does well
The faint deep sky, seen from the suburbs. And citizen science: asteroid occultations, exoplanets, comets.
Strong points
- The largest diameter after Celestron's Origin: the detail follows.
- It clears light pollution well, the halo of towns. It is the brand's founding argument.
- The observing network: the data feeds genuine scientific campaigns.
- The software has been supported without a break since the first delivery, in December 2019.
Weak points
- No dual-band filter inside. Emission nebulae, the clouds of gas that shine on their own, ask for more exposure than a DWARF 3.
- Nine kilos, plus a dedicated tripod. This is no longer a rucksack device.
- It costs more than four and a half times the price of a DWARF 3. The use, though, is much the same.
- The field is narrow, which means what you see at one go. The large nebulae do not fit in the frame.
In practice
Starting out, observing, setting up
-
01
The framing is circular. The original caption takes up the arc at the bottom: allow for the space.
-
02
Under a suburban sky, reckon on 20 to 40 minutes. That is what it takes for a faint galaxy to lift out of the noise.
-
03
The device finds its own way around the sky. You do not aim: you pick the object from a list.

What it really produces
Here is what this device gave in my hands, over 4h 08m of exposure. No manufacturer image, no stock image. Each thumbnail keeps the aspect ratio of its sensor.

The prices are indicative and recorded in 2026. A specification wrong or out of date? Report it. The field of view and the sampling are not published here. The physical size of the sensor is not part of the project's sourced data, and those two values cannot be estimated.
Some of these sources are the pages of resellers selling the same device as me. They stay cited: that is where the figure comes from. Removing them would make this entry impossible to check. I refuse to do that.
