WebJul 26, 2024 · The resolving power of a telescope can be defined as the inverse of the smallest angle subtended at the lens aperture by two point objects at a far away distance from the point of observation which can be distinguished to be “just separate” in that focal plane. The mathematical formula can be given as, θ = D d. WebThe magnifying power MP of a telescope is the (apparent) increase in the size of an object relative to its size when viewed with the unaided eye. MP is equal to the magnitude of the angular magnification m θ = -f 1 /f 2 . The ratio of the diameter of the entrance pupil to the exit pupil is also equal to MP. hospice of lake norman davidson nc
