I would like to learn when to use which chart. There are natal charts, relocation charts, transits, progressed, solar arcs, solar return, lunar return, horary, synastry (bi-wheel, composite, Davison, first meeting charts), etc... It seems that for any given occasion one can start looking at at least a handful of different charts to try to draw conclusions. This is when things start getting fuzzy, with people seeing things that they want to see instead of what they should see. Are there any general guidelines as to which charts should be used first, second, last, or not used at all for a given situation? Thank you!
