I actually watched it twice because there was so much in it. What amazes me most is the depth and breadth of the research he did into both Biblical study and astronomy. Herculean indeed! The man was on a mission.

Stary Night is also a cool tool as is the tool I use on my PC (Stellarium). I plug in my latitude, longitude and elevation and I'm good to go. I can project backwards and forwards, though I never tested how far in either direction, but considering it uses standard formulas of celestial mechanics... I just tested it and went back to the year -2 (BC!). LOL!
