Sky Safari 6 pro is a really great program! Thank you!!!
Yesterday I downloaded the add-on for the Apollo missions. Works fine - the texts under "in-app-purchase" are in english and they are also fine for Apollo 11.
When I looked up the Apollo 11 Mission with the search function a German text is displayed. The German translation was obviously done by a (lousy) translation tool. It's really bad... "trans Mondspritze" for the injection from earth orbit to the moon ("trans lunar injection") is just one "highlight". Mentioning the USS Enterprise in the chapter "the Eagle has landed" another one ;-)
