I have yet to try lunars, but am slowly moving in that direction.  If I
understand the basic concept, we are looking at two bodies that cross the
sky at different rates; Sun 15d/hr, Moon 14d 19', stars 15d 02'.5, and
planets.  Perhaps a question born from ignorance, but could the Sun (close
to ecliptic) and Moon be used as well?
