Unistellar eVscope 2 N-114/450mm telescope with carrying bag

Telescope Unistellar eVscope 2 N-114/450mm

Unistellar's eVscope2 is an ingenious enhancement of the traditional GoTo telescope through state-of-the-art technology to form one of the fastest and most intelligent GoTo systems ever made.

The telescope collects faint light from distant galaxies and nebulae, is collected by a high-sensitivity sensor in low light and refined by unique image processing technology. Using a modern OLED display, the enhanced image is then projected through the eyepiece.

This combines the advantages of computer-aided telescope control and image enhancement with classical observing.
In addition to revealing the mysterious beauty of distant galaxies, the eVscope also allows you to collaborate comfortably with researchers.

Join a vast community and become part of a distributed telescope network to contribute to important scientific discoveries, all while having fun observing.

Digital technology and the development of applications on smartphones/tablets have changed the world of Astronomy in recent years. Unistellar, a French start-up company, has taken this philosophy a step further by making its telescope a concentrate of patented technologies. The eVscope (Enhanced Vision Telescope) is the result of 5 years of research and development by 4 Frenchmen to allow everyone: beginners in Astronomy or simply curious of the sky to discover space and its wonders... without having any knowledge in this field. For amateurs or experts, the eVscope represents a quick solution to add to your equipment.

The eVscope 2 is a 114 mm diameter telescope (size of its primary mirror) on a motorized dual-axis altazimuthal mount, in a "Newton" configuration with a digital camera in place of the secondary mirror. The image captured by the camera (ultra-sensitive IMX347 sensor) is transferred to an on-board computer that returns the image via an algorithm to your tablet or smartphone. Another defining feature of the eVscope 2 is the electronic eyepiece, developed by Nikon: the combination of a state-of-the-art micro OLED display, designed to enhance contrast and provide a perfect black image, and a sophisticated lens assembly, sourced from Nikon's expert optical laboratories. This new "eyepiece" provides captivating, immersive viewing with rich contrast, enhanced viewing comfort and reduced eye fatigue.

Intelligent, easy-to-use telescope

Just turn it on, select the observing target in the app, and you're ready to go. No complicated polar alignment or prior knowledge of the night sky is required. The eVscope2 is automatically guided by an internal compass, an accelerometer and plate resolution. Control of the eVscope is wireless and intuitive via smartphone or tablet using the Unistellar app (Android/iOS). The integrated battery lasts overnight, up to 10 hours. It avoids cable chaos and having to carry an external battery.

Thanks to the "Unistellar" app on Google Play Store (Android) or iOS (Apple), choose the imaging mode (Enhance) to accumulate the light from a galaxy, nebula or comet for several minutes to photograph it in detail. The eVscope takes care of preprocessing (to limit noise) and processing. The longer it sits, the more shapes appear and the contrast increases. Making visible objects invisible to the naked eye.

Autonomous field detection

This outperforms conventional GoTo. Thanks to the sophisticated plate resolution process of the eVscope2, it can analyze the stars in the field of view within seconds, and thus calculate the current alignment of the telescope. Thus, at the push of a button, every object is located and tracked with extreme precision in the night sky.

One of the pitfalls of "traditional" telescopes is their set-up (initialization). The eVscope offers the simplest solution available. After having connected your smartphone in Wifi to the eVscope you point at any region of the sky with the virtual joystick. It then performs an automatic recognition of the pointed field by comparing it with the 10 million stars in its database. In a few seconds, the device is configured and equipped with tracking (compensation of the Earth's rotation), you just have to choose from its catalog of +5,500 celestial objects: a planet, a comet, a galaxy, a nebula or a star cluster.

Ergonomically, the eVscope is so compact that it fits in a medium-sized hiking backpack (included), making it the ideal companion for impromptu observing evenings, even on vacation. A tripod is included as standard, as well as a Bahtinov mask (in the dust cover), which is a very useful tool for adjusting focus (image sharpness).

Improved viewing technology

With conventional telescopes, faint objects, such as nebulae and galaxies, are barely recognizable as faint points of light. With the eVscope, it is sufficient to activate live stacking. The telescope then displays not only the image of a single moment, but collects light over longer periods of time. After a few seconds you will see your observing target as through no other telescope of this size. You can watch live as the image becomes more intense and sharper over the course of a few minutes. The colors and structures of the observing target become clearly recognizable.

Robust optics

The Newtonian telescope with an aperture of 114 mm and a focal length of 450 mm has a fast aperture ratio of f/4. Thus, a particularly bright image lands on the sensor. The parabolic primary mirror creates an image without spherical and chromatic aberrations. The Bahtinov mask integrated in the dust cover makes focusing child's play. Even without experience or prior knowledge, a sharp image is obtained in a few simple steps. The eVscope includes a Sony IMX347 sensor instead of a secondary mirror. This CMOS chip is also used in many high-sensitivity astronomical cameras because of its very low readout noise. The image captured by the sensor is processed by the eVscope and displayed in an eyepiece. An OLED display with an extremely high contrast ratio is used. The experience is very similar to that of a live observation, like that of a purely optical telescope. Of course, the observation target is also displayed on your smartphone or tablet.

Collaboration with SETI

In collaboration with SETI you can contribute to scientific discoveries and become part of a global network of eVscope2 telescopes. The image data from your eVscopes help scientists in the exploration of supernovae, comets and asteroids.
