Flat Earth Celestial Clock v3.2 - 16 years in 12hr intervals
Technical details: Sun and Moon altitudes determined using several methods. Mercury and Venus altitudes are fairly accurate but are still being tested. The rest are correct within their range ratio (using arc seconds calculation) but are not necessarily in their altitude position. More tests need to be done.
VERSION WITH NO ATMOSPLANIC REFRACTION

Flat Moon, Sun and Stars. Planets will be flattened in next version. Needed because the refraction in the atmosplane makes spherical objects look egg shaped. If they are flat, this doesn't happen because it's the vertical dimension that is most effected by refraction.
