How to Calculate Length of a terrestrial telescope?
Length of a terrestrial telescope calculator uses Length of the telescope=Focal length of the objective+4*Focal length of the erecting lens+(Least distance of the distinct vision*Focal length of an eyepiece)/(Least distance of the distinct vision+Focal length of an eyepiece) to calculate the Length of the telescope, The length of a terrestrial telescope is the sum of the focal length of the objective lens, the focal length of the eye-piece lens, and the focal length of the lens placed between objective and eye-piece. Length of the telescope and is denoted by L symbol.
