Galileo's Dialogue in German?

I'm looking for information on a modern German translation of Galileo's 
_Dialogue_ (Concerning the two chief world systems, but that's not part of
the title :)

The edition I'm thinking of, if it exists, would have been published in 
the early 1980s; but anyway it's unlikely there are two. I've made a 
cursory search for this, but my book-searching skills in German are not 
high.
