Reflector telescopes. kindof a dumb question? - how reflector telescopes work
Observed through a telescope, you see the secondary mirror? I mean, you do not block the center of vision.
I've never seen a hand, and have always wondered.

No, you do not see the mirror.
Due to the curvature of the primary mirror on the back of the cell, the incoming light rays to a point outside of the tube into the body of the scope, which will focus on the eye focus.
The secondary mirror does not block part of the incident light, however, that the results in a bit weaker than you would have seen through a refractor.
Hello. In fact, see everything you do. The primary mirror is a reflection.
It seems fair to fill in. No problem.
No, because it is so close and not for discussion.
Imagine looking in the window screen. A few steps, you can easily see the screen, but if your face against it is hardly visible.
Yes and no. In the concept and not noticed the presence of the secondary mirror, but with stars such as donuts focus will be sought. This is normal for all reflector telescopes, with the exception of a few that, in other words, nothing in the way of the light means emerged. The loss of the light is low, but not serious, because the average diagonal Newton in most blocks, a small percentage of the incident light. Also, the center of the primary mirror in May show a gap that the mask of the secondary mirror, the incident light, thereby reducing the impact on the views that see through the telescope.
Only when the focus is on the street and you see the full moon. Planets do when you are out of the discussion. However, the radius
May paths run throughout the primary mirror secondary mirror.
