Solar Eclipse Composite

Das beste Bild einer Sonnenfinsternis, das ich jemals gesehen habe: The Crown of the Sun. Ist ein digitales Composite aus 7 Bildern, aufgenommen während der Sonnenfinsternis auf den Osterinseln neulich.

During a total solar eclipse, the Sun's extensive outer atmosphere, or corona, is an inspirational sight. Subtle shades and shimmering features that engage the eye span a brightness range of over 10,000 to 1, making them notoriously difficult to capture in a single photograph. But this composite of 7 consecutive digital images over a range of exposure times comes close to revealing the crown of the Sun in all its glory. The telescopic views were recorded from the Isla de Pascua (Easter Island) during July 11's total solar eclipse and also show solar prominences extending just beyond the edge of the eclipsed sun. Remarkably, features on the dim, near side of the New Moon can also be made out, illuminated by sunlight reflected from a Full Earth.

Und worüber ich mir auch noch nie Gedanken gemacht habe, formuliert einer auf Reddit so:

You know what always blows my mind?

There's no reason why the moon and the sun should just happen to have the exact same apparent size in our sky, but they do. It's totally by chance and it makes for really awesome solar eclipses.

Hat dafür jemand 'ne Erklärung?
