Which astronomical instrument did Wernher Von Braun use?

Answer 1

In a sense he did not design any, but did adapt a wrist watch so it could be used- with reversed printing, to track the shadow of ascending rockets in conjunction with a Maritime Sextant ( Navigational instrument) the observer took a sighting on the ascending rocket and made the appropriate notations on his Observation Watch- or BeobachtungsUHr- which is a literal German Translation. ( Beobachter meaning observer- common Newspaper moniker) these modified B-dienst ( observation service) watches were made for the War Ministry and were termed Sextantuhr- or sextant watches, for use with the Sextant- and were custom made. Von Braun designed these things. Deutsches Optik sold a few last year, naturally these were grabbed up- nowadays all sorts of electronic computers follow the rocket shots- but then. hand and eye and some quick figuring!
