What about Mars magnification?
Am I missing something? Is my arithmetic off? Presently Mars is some 20 arc
seconds wide. This implies that at 100 X's magnification, it should be 2000 arc seconds across...or just over 1/2 a degree, which is the diameter of a full moon!! (1/2 degree = 1800"). Last night, the image at 100 x's is no where near the size of a full moon. What am I missing here??
