Chinese scientists also expect to install a wide-angle telescope in Dome a in the next 2 years.

明后年，中国天文学家将把广角望远镜架设到冰穹a上用于天文观测。

You'd find that you have to turn the telescope at a slight Angle to line up the object.

你发现必须把望远镜转一个轻微的角度以和该物体对准。

Firstly, a telescope system is made up with a concave lens and a long-focus convex lens, by which the angle of the parallel beam from the collimator can be change.

该方法借助一个焦距较长的凸透镜与被测凹透镜组成无焦系统，可以使准直管出射光束的张角发生改变；

It works because the maximum resolution of a telescope (the minimum angle apart that two points need to be for the telescope to see them as separate) depends on its diameter, not its collecting area.

ECONOMIST: Radio telescopes

At its best, RadioAstron will be able to resolve points separated by an angle of just 7 microarcseconds, about 10, 000 times the resolution of the Hubble Space Telescope.
