An excellent video about Venus transits was just posted last week sharing stories about Venus transit observers from centuries past — including Captain James Cook (who sailed to Tahiti to observe the 1769 transit) and the team of Charles Mason and Jeremiah Dixon (who observed the 1761 transit from Cape Town, South Africa before becoming household names surveying a famous borderline between Maryland and Pennsylvania).
The video also contains some tips for observing Venus in transit in June. It contains a serious reminder, too: Never look directly at the sun using a telescope or binoculars. If you have a solar filter on your device (something that looks like a sheet of tinfoil covering the front of the scope), that’s another matter. But this warning is really important. Looking directly at the sun, especially through anything that magnifies the sun’s light like a telescope or binoculars, can cause severe and permanent eye damage.
