I am working on a project and need information on SHA & dec changes
for stars. I want to replot some star on my 2 minute star finder to recheck
sighting postions on the old mill in Newport RI. Mill may have been built
year 1500. How much star changes? The noticed change SHA & Dec is interesting.
Any old date year will give clue if not 1500.
