Suppose a telescope is constructed with a 20-cm focal length objective and a 10-cm focal length eyepiece, but that the observed object is at a finite distance from the telescope (say, on the other side of a room) instead of an infinite distance (somewhere out in space). To bring the object into focus, will you need to put the objective and eyepiece closer than 30 cm away from each other or farther away? BONUS: What will be the (qualitative) effect of this adjustment on the telescope's angular magnification?
