(ECNS) Astronomy fan Yan Mingzhe hails from Anhai Town, Jinjiang City, Fujian Province. He managed to create a Newtonian telescope all by himself.
He polished two large-diameter lenses and a star-tracking device.
One of the lenses is 400 millimeters in diameter, the other, 500 millimeters. Few Chinese astronomy enthusiasts can grind such a large lens by themselves, and few can build a matching tracking system , while even fewer can learn to make both, he said.
Yan became interested in astronomy when he was a junior high school student. Now, he can produce one lens in one or two months.
