A telescope has an objective of diameter 60 cm.The focal lengths of the objective and eyepiece are 2.0 m and 1.0 cm respectively. The telescope is directed to view two distant almost point sources of light, (e.g., two stars of a binary) The sources are roughly at the same distance = ( =10^4 light year) along the line of sight but are separated transverse to the line of sight by a distance of 10^10 m. Will the telescope resolve the two objects i.e. will it see two distant stars?
