WebJun 20, 2024 · The formula for calculating Dawes’ limit is R = 116/D D is the diameter of the telescope aperture in millimeters R is the angular size in arcseconds. Most home telescopes have an aperture of around 8 inches. So its Dawes’ limit would be: R = 116/203.2 – The Dawes’ limit is 0.57 arcseconds.

WebFor example, in the case of yellow light with a wavelength of 580 nm, for a resolution of 0.1 arc second, we need D = 1.2 m. This formula, for light with a wavelength of about 562 nm, is also called the Dawes limit.
