Jupiter war gerade in Opposition, also auf seiner Umlaufbahn der Erde am n\u00e4chsten. Dass diese Opposition in den Sommer f\u00e4llt, war allerdings nicht von Vorteil, da der Jupiter dadurch tiefer am Himmel steht als bei einer im Winter.<\/p>\n

Hm, sehe ich da einen Farbsaum? Oben Blau und unten Rot? Das war mir schon bei anderen Aufnahmen mit dem Mak aufgefallen. Hatte mir halt gedacht, dass das Ger\u00e4t eben doch nicht so farbrein ist wie erwartet. Das war ein Denkfehler! H\u00e4tte mir schon fr\u00fcher Gedanken machen sollen, warum denn der blaue Rand immer oben ist, woher soll der Mak wissen wo Oben ist?? Dieses Ph\u00e4nomen heisst “atmosph\u00e4rische Refraktion<\/a>“, blaues Licht wird von der Luft weniger stark gebrochen als Rotes. Bislang war ich mit diesem Effekt nicht konfrontiert worden, weil meine Teleskope selbst f\u00fcr Farbe gesorgt hatten.
\nMan kann das per Bildbearbeitung ausgleichen:<\/p>\n
