**drwls**, Thursday, June 21, 2012 at 5:19amThe power of the telescope is the ratio of objective to eyepiece focal lengths.

The power of a telescope is the factor by which the subtended angle of an object is increased, when the eye is focused at infinity.

The powers available in this case are

2000/40, 2000/16 and 2000/8. That converts to 50, 125 and 250.
