What I mean is, at 100 X's Mars is to appear as the moon does unaided.
The two are supposedly equivalent. (1/2 degree) Now, if you up the anti
to 200, Mars should be equivalent of what the moon would appear to be
at 100 X's....in the EP.

No it shouldn't. What others have said to you is correct. Read and
understand it; don't just dismiss it because you don't like it. It is a
tad disrespectful to ask a question then just dismiss the responses you
get in this manner. Restating your original error in different words
will not make it correct, no matter how many times you do it.

At x200 Mars will have an apparent diameter of about a degree. At x100
the Moon will have an apparent diameter of about 50 degrees. There is
exactly no way in which these can be equivalent.


Your first paragraph is far more "terse" than anything I have written so far
and unnecessary. You exaggerated your perception
of my communication...

However, your second paragraph exposes my error in logic...I really don't
care if I am wrong! I am just trying to get
at the answer..AND, the answer is this: My mistake is my perception of
magnification. To make Mars appear the same as a 100 X's magnification of
the moon I would have to take the 100 X's image of Mars and magnify the
image another 100 X's. This is not the same as 200 X's magnification. In
other words, I would need a 100 Xs ZOOM to achieve this.
