If the numbers are correct then the FOV is correct.

FOV in deg =57.3(width of sensor/focal length) .
One radian =57.3deg.
as long as all dimensions are the same units.

and Moon diameter 3476 km
assume 0.5 deg apparent angular size

so (0.024/0.5)X3476 = 167 km for 680 pixels

so 167/640 = 0.260 km per pixel

So each pixel is 260M
If we assume the niquist theory is correct that you have to sample at half the distance of the wanted resolution then your best theoretical resolution is about 500m. I think that is amazing.
