Indeed, it would be truely difficult to make precise observations with 
this kind of device. Actually, there was an other, simpler instrument 
called "astronomical ring" that could serve such purposes. See 
http://www.galerie-kugel.com/expo_en.htm for some beautiful pictures of 
those instruments. I saw the exposition, and it was amazing...
