General Forum Message . Forums: . ... The Telescope's F/number . ... The f/number (focal ratio) of any telescope tells two things about the telescope and that is it's intended purpose and it's photographic performance. The brightness of a star depends on the telescope's aperture not the telescope's f/number. ... The f/number of any objective lens or a mirror of a telescope has nothing to do with the visual brightness of an image, the bigger the aperture the better. ... www.astronomy.net . ...

For non-spherical isotropic particles, the classic variant of the RDG approximation does not include the anisotropy of the shape and hence does not give the correct Rayleigh limit, say, for small ellipsoids. ... We call this variant a modified RDG approximation (MRDG). ... First, the MRDG leads to the correct Rayleigh limit. ... The second approach to generalization of the RDG is connected with the use of the Born iterations for the scattering integral equation [ 95 , 124 , 132 , 264 ]. ...
