Thanks Greg,
That is brilliant.
So I guess Capt Cook was a pretty tall sailor for 1769 ( 6'2" I think? Wonder if he kept banging his head on the 4'6" high oak beams?) .So say ht of eye about 2m gives dip -2.5'. assuming he is standing roughly sea level on land? The Endeavour pictures of Venus Point observatory look pretty low, about sea level?
Sun SD and ref correction +15', so taking Hc 50°5.3' and applying corrections in reverse, gives Hc -12.5' =49° 5.3' for Cook' Hs, assuming no IE?
I'm probably miles off. Sticky neurone syndrome bad this am and no sleep!
Anyways,very good picture and challenge, which I guess Dave wins, having correctly guessed the Venus transit first.
Best
Francis
