An observers unaided eye has a resolving power of 120 seconds of arc. Using a telescope of angular magnification of 24, what would be the agnular separation if the same observer used the telescope?
Simple question, but I get it wrong?
Could you tell us
How you got it
The "correct" answer?
Thanks Stonebridge - I've got it now. Just this question is a bit different than the others I've seen ... the subtended by the eye means once seen through a telescope the angle at the objective lens is reduced - I had it the other way around.
