In this example we are only concerned with what the front surface of

could be a Newtonian primary mirror which would be _more_ distant from
the object than is the eyepiece.

Aha, good point.

But still, it's not clear to me why the only distance that counts is
the one between the object and the objective lens (or primary mirror).

I guess I'm going to have to go learn about it by actually reading a
textbook and doing some exercises.
