The 2nd one is purpose diameter of the lens system. With glorious object length the representation you see through with the field glasses is brighter. This cipher is overlapping to magnification and the best quantitative relation is one to five. So if you are looking at opera glasses near magnification of 8, the longest lens diam would be 40.
