Question

An astronomical telescope is being used to examine a relatively close object that is only 126.00 m away from the objective of the telescope. The objective and eyepiece have focal lengths of 1.120 and 0.0930 m, respectively.

Noting that the expression M = - fo/fe is no longer applicable because the object is so close, use the thin-lens and magnification equations to find the angular magnification of this telescope.
