Problem: your camera can't measure the light correctly. It measures full frame mostly (if you haven't selected "centre weightened" or "spot" metering). The camera overexposures the Moon coz it measures the darkenss around it.
Solution: go to manual mode of camera (if you have one?). Focus it to infinity (i.e. landscape mode). Then put aperture some f5.6-11 and try shutter speeds at 1/125, 1/500 or even 1/1000 second at lowest ISO50-200 sensitivity you have. You can do it from HANDS, because the shutter speed is so fast!
After taking pic zoom in from picture preview mode to see if the Moon got any details or not. Then you'll see if the Moon is overexposured or underexposured, then adjust shutter speed accordingly [if too bright, no detals -> faster shutter speed (i.e. you had 1/125 then put 1/500 or 1/1000 second)] [if too dark, nothing visible -> put slower shutter speed] till you get the result that is comparable with your own eyes.
Lemme know if it got better!
