A silly question on how a newtonian telescope works

Ok, this might sound silly and there's probably an easy explanation, but here is my question...

You know how at the sky end of the newtonian telescope where the light enters, the very centre is taken up by the holder for the mirror to the eye piece? Why then doesn't the image you see show a blacked out central region in the field of view, being the area obstructed by the small mirror for the eyepiece?
