WebThe largest-focal-length eyepiece you can use with your telescope is easy to calculate: multiply the focal ratio (the focal length of your scope divided by its aperture) by 7. For example, your Newtonian scope is f/5: the largest … WebWe can calculate the distance where the image is produced by applying the formula for converging lenses: 1 x o + 1 x i = 1 f → x i = 1 1 f - 1 x 0 = 1 1 10 c m - 1 30 c m = 15 c m. Since the quantity is positive, the image is formed on the opposite side of the lens and upside down. We can calculate the magnification as.
