Atmospheric Effects on Starlight and Sunlight,and reddened by the atmosphere. The Sun makes an excellent probe for studies of atmospheric effects; it is especially useful for studying refraction, extinction, and color effects that occur near the horizon and the polarizing property of the atmosphere.

Photography of the Sun and Stars,Here we begin discussing the radiant energy from natural cosmic bodies, in particular from the Sun and stars. It was recognized that distances could be found through comparisons of brightness well before the first measurement of stellar parallax by Bessel in 1838. We begin where Johannes Kepler first explored—with the inverse square law for light.
