Neue Seite fuer Mond-Planeten-Bedeckungen mit Jahresberechnung hinzufuegen

Browse Source 
Berechnet Bedeckungen der Planeten Merkur bis Neptun durch den Mond fuer
ein ganzes Jahr am Standardstandort, inklusive Detailkarte. Ereignisse
unter dem Horizont werden weiterhin angezeigt statt gefiltert, dafuer
mit eigenem Sichtbarkeits-Hinweis.
