The apparent magnification of telescope optics is
(focal length of the objective) / (focal length of the eyepiece)
= (1,000 / 25) = 40 .
The diameter of the primary mirror has no effect on the apparent magnification.
The length of the body tube is involved in the case of the Newtonian configuration,
only because it has to be long enough to hold the eyepiece in the right place.
