WebNov 4, 2024 · The focal length (f) is the distance between the lens and the focal point. Because the focal length measures a distance, it uses units of length, such as centimeters (cm), meters (m), or inches... WebTrue Field of View. Eyepieces also determine the true field you see in the sky. To calculate the true field of view that you will see (in degrees), divide the eyepiece field stop diameter by the telescope's focal length and multiply the result by 57.3: True field of view = eyepiece field stop diameter ÷ telescope focal length x 57.3.
