It has already been said that we cannot give an answer and it's starting to appear that in your case, that means we cannot help.Emilyjoint said:if you cannot help/give an answer just accept it and say so.

There's no better place than here.Emilyjoint said:Where else can help be found for physics problems?
It is your fault actually. People have been giving you hints that are very close to a complete answer, and you just get irritated and ignore them every time. Things would have been different if you had tried to answer their questions instead of just suggesting that they shouldn't have asked them.Emilyjoint said:How Is it that more stars can be seen though a telescope?
I am afraid that the contributions here have been of little help.
It must be my fault
Diffraction does make the image larger but not in a useful way. If the telescope could focus perfectly, the image of a point source would be a point; however, because of diffraction, actual telescopes smear the light from a point source into a smudge. In other words, because of diffraction, the image from a telescope will always be slightly out of focus. You've probably seen a movie or a picture that was out of focus. The image of an object is larger in an out-of-focus picture than when the picture is in focus, but the larger size doesn't help you see the object more clearly. In fact, an object is often harder to see because its image overlaps with the image of other things in the picture.Emilyjoint said:I am lost ! I think that the telescope does make the image of the star larger...isn't that what the diffraction pattern is.
That is the only thing that I can think of that makes it possible to see more stars.
