Answer 1

Instrument with 0.001" precision of angular spacing.

Explanation:

1" = 1/3600 deg. Mean distance of Moon is about 3.84 E+05 km.
The precision for viewing equipment on Moon that is 20 meter wide:
2 X arcsin (.01/3.84 E+5) = 3. E=06 deg = 0.01 sec, nearly The smaller 0.001 sec precision is suggested..
