JohnS Magnification depends on the focal length of the objective (main lens) and the focal length of the eyepiece. The focal length of the objective looks to be about 300mm, so, with an eyepiece with focal length, say, 10mm, the magnification would be 30X. (F1÷F2) The Barlow lens usually multiplies by 2 and the erector lens by another 1.5X, so 90X by then. A shorter focal length eyepiece will increase the magnification still further.
