Hi all --
Last year, over a period of weeks, I observed Mars' retrograde motion and was amazed by it. Has anyone tried to measure planetary motion (retrograde and otherwise) using a sextant or other device? I know that the planetarium programs show platetary movements very nicely but I'd like to document the movements myself.
