    They use a mirror to gather the light. Then, with a secondary mirror at a 45-degree angle, they send the light to the eyepiece.
  • Lens Diameter 76 mm

  • Focal Length

    It is the distance that light rays need to travel to reach the focal point, that is, the sensor of the lens.

    The shorter the focal length, the wider the angle of view for the photograph, and therefore, the more of what is in front of us the lens can capture.
