Camera Sensor Field of View

The angular field of view determines how much sky the sensor captures.

Formula

FOV = 2 arctan(d / 2f)

  • *d* = sensor dimension (width or height) in mm
  • *f* = telescope focal length in mm

    • Convert from radians to degrees by multiplying by 180/pi.

    हल किया गया उदाहरण

    APS-C sensor (23.5 mm width) on a 1000 mm focal-length scope.

    1. FOV = 2 * atan(23.5 / 2000)
    2. FOV = 2 * atan(0.01175)
    3. FOV = 2 * 0.01175 rad = 0.02349 rad
    4. FOV = 0.02349 * 180 / pi = 1.346 degrees
