Yes you can measure the altitudes of stars using water in your artificial horizon, I took five sights of Sirius and five sights of the brighter Jupiter last Sunday night. But I was not able to find Polaris reflected in the water but had no problem doing so with my mercury horizon.. Second point. For someone who wants to build a permanent artificial horizon it occurs to me that my idea of using a liquid that levels itself and then solidifies (I was suggesting water in the northeast this winter) might work. Is there some substance such as glue that will flow, level itself, and then harden (and not melt later) that has a reflective surface? gl --- On Tue, 1/25/11, George Huxtable <george@hux.me.uk> wrote:
