what is the difference between linear magnitude and angular magnitude
never heard of either in reference to telescopes
and I have used scopes for best part of 50 years
please give more information
my question is this:
Wait, do you mean magnification, not magnitude?
Sorry i meant magnification.
Angular magnification is what our eyes or a lens see, whereas linear magnification is what is projected onto a surface, so it is measured linearly.
See (second section):
Since this is a telescope question, I'm moving the thread to that section.
the other question i have got is: where do these formulas like field of view and .... come from
I assume you mean, how is it calculated ?
What is the prove of that FOV?
It's derived from basic trigonometry. The angles and objects form triangles.
