The owner of a pub in Hanoi has succeeded in making a telescope, which now enables customers to simultaneously sip wine and contemplate the craters on the moon. He is Trinh Van Hai, 41 years of age, and the owner of Tu Hai Pub in Hamlet 124/55 off Au Co Road. His pub is done in the style of a wine restaurant of ethnic minorities. Customers sip wine on a flowery mat under a thatched roof. Waiters wear traditional clothes of ethic minorities. A few months ago, it occurred to Mr. Hai to organise an Astronomy Night for customers to enjoy the taste of wine and the sight of the moon. But telescopes imported from the US or Europe are too expensive; Chinese telescopes are cheap, but not of the right sort. So Mr. Hai, a former mechanical engineer at Hanoi Polytechnics University, was determined to make a telescope of his own.
