When you reach beta, you'll find that the Large Magellanic Cloud has just crept into your FOV. Beta Doradus is a bright Cepheid, changing its magnitude from aboug 3.3 to 4.7 every 9.8 days. The star's colour goes from a creamy-white to a golden colour as it reaches its minimum brightness. The star is about a thousand light years away.
