Summary[edit]
DescriptionMilchstraße über den Externsteinen.jpg |
Deutsch: Die Externsteine bei Horn sind nicht nur eine sehr ungewöhnliche Felsformation, sondern das Areal ist auch recht wenig von "Lichtverschmutzung" betroffen. Daher lassen sich hier nachts auch sehr gut Fotos mit der Milchstraße/dem Sternenhimmel anfertigen.
Diese Bild entstand aus einer Aufnahme von 10 Sekunden Belichtungszeit, bei der die Felsen mittels einer Taschenlampe für weniger als eine Sekunde angeleuchtet wurden. Um die Struktur der Milchstraße herauszuarbeiten und das Bildrauschen zu reduzieren, wurden 15 unmittelbar hintereinander gemachte Aufnahmen übereinander gelegt (Stacking). |
