The focal length from the astronomical telescope is fO, and also the eyepiece’s focal length is fE. In this development, the aperture of the objective lens is taken mostly when compared to the eyepiece to ensure that far more mild is often obtained by it from distant objects plus a brighter impression is often formed.
