   The true field of view (TFOV) is how much of the sky you can see when looking through your telescope with any particular eyepiece in place. You can calculate the true field of view of a telescope + eyepiece combination using the following formula: True field of view = Apparent field of view / magnification

   12 gru 2022 · To calculate the field of view of a telescope, you will need to know the focal length of the telescope and the eyepiece used. The formula for calculating the field of view is: For example, if you have a telescope with a focal length of 1000mm and you are using an eyepiece with a focal length of 25mm, the field of view would be:
