  • Page 17 Connect your eVscope 2 to the Unistellar App, using WiFi Launch the Unistellar App, and authorize the App to access your WiFi settings (or acti- vate your WiFi on your device). The App will automatically detect your nearby eVscope Select your eVscope 2 from the list of network...
  • Page 18 Press the Autonomous Field Detection (AFD) button and the eVscope 2 will instantly recognize objects in its fi eld of view. Choose the fi rst recommended object in the catalog of the App and hit the Go to button, it will take you directly to the object.
  • Page 19 If there is a diff erence in temperature between the outside and the room your eVscope 2 is stored in, turn on your eVscope 2 and put it outside about 15-30 minutes prior to your observation, depending on the temperature diff erence.
  • Page 20 Go to the fi rst recommended star in the catalog as it will be the brightest available to you. Separate the Bahtinov mask from the cap cover. Place it on top of the eVscope 2 tube, and turn gently as needed to fi t it onto the tube.
  • Page 21 How to take a dark frame ? To take a dark frame, keep the cap cover on the eVscope 2 and make sure you are in dark surroundings. Don’t expose the eVscope 2 to direct streetlight.
  • Page 22 Collimation If you are having diffi culty achieving focus as outlined in previous sections, or if you are struggling to achieve a high-precision focus using your Bahtinov mask, your eVscope 2 may require collimation. What does collimation mean? Collimation refers to the process of aligning the optical axis of the mirror (located at the bottom of the tube) and the sensor (located at the top of the tube).

  • Page 24 What is AFD ? Autonomous Field Detection (AFD) is an algorithm that uses an internal map with tens of millions of star coordinates to accurately identify any object in the eVscope 2 fi eld of view. What does the AFD do ? The AFD points at objects in the night sky automatically, making it easier to fi...
  • Page 25 Enhanced Vision while using. Software The eVscope 2 software uses its on-board computer to stack and process frames (dark and background removal, shift adding and stacking). It produces an improved image and projects it in real time with a derivation algorithm that compensates for the earth movement / rotation.
  • Page 26 They can’t be seen better than with a classical telescope, except for Neptune and Uranus which are very far and fainter. Use the Go to button to point the eVscope 2 at the celestial object. Gain (dB) and exposure time (ms) will be automatically adjusted in order to view the Moon or planets.
  • Page 27 5 - 20 GPS and Localization You can use the eVscope 2 on a balcony or in a garden, in the city or in the country. We recommend at least 45 degrees of open sky. Diff erent factors come into play based on your location which can aff ect the quality of observations, for example: quality of the night sky, position in the Bortle scale, light pollution, atmospheric interference, altitude, and position compared to the equator.
  • Page 28 The data collected by the eVscope 2 at each observation is stored in its memory and includes raw data (frames) of the objects observed in Enhanced Vision or during Science Missions, as well as metadata (geolocations, timestamps).
  • Page 29 Click on ” Submit ” and the eVscope 2 LED will turn from red to a blinking bright yellow ( the eVscope 2 is trying to connect to the selected network ). Your device will no longer be connected to the eVscope 2 and information like the name or storage usage won’t be accessible in the app.
  • Page 30 Detecting an asteroid’s occultation entails observing an asteroid passing between a bright star and your position on Earth. The blinking of the star recorded by the eVscope 2 provides valuable data so astronomers can learn more about the trajectory, size, shape and composition of an asteroid.

    Travelling with the eVscope 2 If you need to travel on a plane, do not put your eVscope 2 in the backpack as a checked luggage ; it might be damaged and it won’t be covered by the warranty. Use a rigid case to make sure your Expert users recom- eVscope 2 stays perfectly safe.

  • Page 33: Troubleshooting

    - Your OS that has WiFi preferences - A communication error between the eVscope & the phone There is no way to boost the WiFi signal of the eVscope 2. Try using an extender with the same SSID as the eVscope 2 to extend the range.
  • Page 34 If you experience connectivity issues, turn off the "auto-connect" options on the other known networks. Issue with the focus : If you do not see the diff raction pattern (the star symbol), manually adjust the exposure time and gain using the Bahtinov mask. Can’t take a dark frame : Try again in darker surroundings and make sure your telescope was left outside for 15 minutes.
