How does a newtonian reflecting telescope work? - why are the images in my telescope inverted
Your new telescope has aroused my curiosity - or more accurately, as it is, if in his eyes we see the cross as one of the diagonal (or the mirror itself?) In the picture mount? I can not get my head around the problem and has been so long since I Optical Physics, I had almost forgotten how it worked ....

Why Are The Images In My Telescope Inverted How Does A Newtonian Reflecting Telescope Work?

The main obstacle is before the light is focused by the telescope. Consider a star around the field of vision. As the ice is the light of this star of views? It should be clear that if one ignores the central obstruction of the light that seems to be a star on the surface of the mirror, not just one point.
While the telescope is working to solve the light rays so that there is a 1:1 ratio between _direction_ beams and _position_ light beams in the focal plane. So in light of the stars in the central field of vision for the success of the edges of the ice and go in the middle of the image along the optical path.
The "hole" in the picture is the image ofm light loss, a regulator of the picture concentrated not in the position of the resulting image.
The eye that covers the surface of the mirror diagonal. It shows the spider in the vicinity of the small diagonal.
The reflections of the primary mirror is at a point where the diagonal is the area piuece the eye placed.The refers only to that area of the diagonal.
You can not wing the spider in front of the mirror, because they are too close. It is too simple an answer. but you can not see, for the same reason you can not see a pencil in front of a pair of binoculars instead. To put this light on a subject should be much further.
