Summary
Dubay's "proof" 150:
150) If Earth were a spinning ball it would be impossible to photograph star-trail time-lapses turning perfect circles around Polaris anywhere but the North Pole. At all other vantage points the stars would be seen to travel more or less horizontally across the observer’s horizon due to the alleged 1000mph motion beneath their feet. In reality, however, Polaris’s surrounding stars can always be photographed turning perfect circles around the central star all the way down to the Tropic of Capricorn.
