The best telescope is the one you use: Discover the Unistellar eVscope 2, the astronomy revolution for everyone
As astronomy enthusiasts, we're often on the hunt for the "perfect" telescope. But what really defines the best instrument? Power, diameter, price? In reality, the best telescope is the one you use . This philosophy guides our exploration of the Unistellar eVscope 2, an instrument that promises to make observing the sky more accessible and more frequent. Is it the ideal tool for both budding astronomers and more experienced ones who lack the time or motivation for complex setups? Let's dive into its performance to find out.

A sleek design, redesigned ergonomics: The Unistellar eVscope 2 from every angle
The Unistellar eVscope 2 stands out for its compact design and ease of transport. Supplied with a dedicated carrying bag, it weighs approximately 10 kilograms (tripod included), making it easy to move. Its design integrates all the necessary components for its operation directly into the bag, a notable difference compared to more traditional telescopes. The ergonomics have been clearly designed for quick and intuitive handling: deploying the tripod, leveling, and securing the telescope are done in the blink of an eye. For users of all sizes, the digital eyepiece, offset at the rear of the tube, guarantees comfortable observation, even with the tripod fully folded. No more contortions or stepladders!
eVscope 2 Optical Performance: When Compactness Doesn't Mean Compromise
The eVscope 2 uses a Newtonian optical design, with a primary mirror measuring 114 mm in diameter . While this may seem modest compared to larger instruments, its aperture ratio is similar to that of larger telescopes. This means that the eVscope 2 is able to collect as much light and produce a bright image as quickly as much larger instruments. Focusing is carried out via a dial on the rear of the telescope, offering satisfactory precision. The integrated Sony sensor, renowned for its high sensitivity handling, ensures impressive image quality, even in low light conditions. Although the eVscope 2's magnification is "only" 50 times, it can produce images of nearly 8 million pixels, allowing for significant digital zoom. While the resolution and detail won't rival a 400mm telescope, many celestial objects that are too large for the narrow fields of view of larger instruments fit perfectly into the eVscope 2's wider field.
Where the eVscope 2 excels is in its built-in astrometry system . Forget lengthy manual alignment procedures or tedious searches for reference stars. The eVscope 2 knows its position and time thanks to the app. In a few seconds, it analyzes the stars in its field of view and compares their position to its database, thus determining its precise location. This “field recognition” process is incredibly efficient, even with a limited field of observation, which is a major asset in urban environments or if the sky is partially overcast. Once located, simply select an object in the app, and the telescope automatically points to it, even correcting its aim if necessary. This self-correction capability is an invaluable time saver and source of comfort, especially for beginners or during short observing sessions. Finally, its ability to "stack" images, called "amplified vision" in the app, significantly reduces noise and improves the brightness and contrast of faint objects. This results in images of nebulae and galaxies that are surprisingly detailed for an instrument of this size.
Advantages and limitations of the Unistellar eVscope 2: An honest assessment for an informed choice
Like any telescope, the Unistellar eVscope 2 has its strengths and weaknesses:
Benefits

Remote and warm observation: control from inside via Wi-Fi.
Boundaries
- ✖
High price: significant investment in the high-end category. - ✖
Limited diameter and resolution: 114 mm mirror, less efficient than a large telescope. - ✖
Limited manual control: Automation can frustrate traditional astronomy enthusiasts.
Final assessment: The Unistellar eVscope 2, an investment for observing the sky more easily
The Unistellar eVscope 2 is not just any telescope. It's an instrument designed to maximize actual observing time by minimizing setup and adjustment requirements. While larger telescopes, such as a 400mm, offer superior raw magnification and resolution performance, they require a considerable commitment in terms of logistics and time. What makes the eVscope 2 so relevant is its ability to turn the "the best telescope is the one you use " theory into a practical reality.
It's ideal for those like me who often find themselves having to abandon an observing session due to cold, fatigue, or lack of time. It's up and running in two minutes. It's perfect for quick sessions or for sharing the experience with a novice audience. Its ability to cope with light pollution and mixed weather conditions makes it a great companion, even in the city or suburbs.
So, do I recommend it? Yes, without hesitation, for anyone looking to maximize their skygazing time. It's an investment that guarantees your telescope won't stay in the closet. It opens the door to more spontaneous, more social, and most importantly, more frequent astronomy. It's the tool that inspires you to look up at the sky more often, and that, ultimately, is the greatest promise for any astronomy enthusiast.
