Telescope Magnification Calculator — Frequently Asked Questions
Q1 What determines maximum useful telescope magnification? ▾
Atmospheric diffraction and aperture size limit maximum useful magnification to approximately 2× per millimeter of aperture (50× per inch).
Q2 Why do images look dim and blurry at excessive magnification? ▾
Empty magnification spreads the same fixed number of collected photons over too many detector pixels/retinal cells, decreasing image contrast and brightness.
