Abstract
For many astronomical applications the Sun has to be placed on a stellar scale. The main problem of a direct comparison between Sun and stars is to cover the range of more than 1012 (30 mag) in brightness. Additional complications arise from the time delay between day and night and the fact, that the Sun is an extended light source while the stars appear as point sources. Ideally the intervening optical elements and the path of light should be the same for solar and stellar observations.
