Document Summary

Much like the human eye: lens manipulates light, retina detects light, (glasses can manipulate but can not detect) *images we take with a telescope tend to be flipped. Big eyes = large light collecting area. Angular resolution of the human eye = 1/60 . Best possible angular resolution = 70 x /diameter (angular size / 360 = physical size / 2 d ) (angular separation / 360 = phys separation / 2 d) Angular resolution: endpoint where you can"t distinguish objects that are close/far (the smaller ar, the better) the larger telescope better ar.
