WebNov 20, 2024 · Used in a telescope with a 1000mm prime focal length, the magnification is 40x. The true field of view is therefore 1.25-degrees (50/40=1.25). The other formula for calculating FOV in degrees involves dividing the eyepiece field stop diameter by the prime focal length of the telescope and multiplying the result by the constant of 57.3. WebMar 28, 2024 · Magnification (Mag) of a scope is ƒ / eyepiece ƒ (focal length / eyepiece focal length) Each telescope focal length has a magnification range that is modified by the eyepieces you use. Common eyepieces range from 10mm to 25mm focal lengths. You can modify the magnification range with Barlow lenses (increasing focal length) or … WebThe objective magnification (M) is calculated by dividing the reference focal length (L) of the tube lens by the objective focal length (F).
