I found in Gauss's biography that I am reading now that he owned a 9-inch Troughton and Simms, but the book gives no more details, except that Gauss liked to use it very much. Apparently he never sailed, but used his sextant just for fun, with "land navigation". In the geodesic surveys he made as a part of his duty as an astronomer he used a Borda reflective circle and theodolites. For astronomical observations in his university observatory, he used meridian circles and transit instruments (some of them apparently are still in the observatory). It is not clear whether his sextant survived to our days. I've seen his observatory in Gottingen, (from outside) it looks completely neglected, and there is no access to the inside, no museum, nothing. Alex.
