Key Features

A. eVscope

  1. Enhanced Vision and Portability: The eVscope utilizes advanced technologies such as Light Amplification by Stimulated Emission of Radiation (LASE), allowing it to capture more light and reveal details that are typically invisible to the naked eye. Its lightweight and compact design make it easy to carry and set up in various locations.
  2. Autonomous Field Detection: With the eVscope’s Autonomous Field Detection (AFD) feature, finding celestial objects becomes effortless. Simply point the telescope towards the sky, and the built-in software will analyze the field of view, identify objects, and display them on the device’s screen.
  3. Live Sharing and Social Interaction: One standout feature of the eVscope is its ability to connect with a dedicated smartphone application. This allows users to live-stream their observations, share images and videos on social media, and engage with a community of fellow astronomers.
