I remembered that the luminance of the moon at that position was about 250 c/ft^2, placing this luminance on Zone VII, i could calculate that 60 c/ft^2 would fall on zone V. With a film if ASA 64, the exposure would be 1/60 second at f/8. Allowing a 3x exposure factor for the filter, the basic exposure was 1/20 second at f/8 or about one second at f/32, the exposure given.... We have all seen the blank white circle that represents the moon in many photographs, primarily caused by gross overexposure. 3. what's happening is that your metering is taking in too much dark sky. if you cannot use a spot meter or other method to isolate the moon, my recommendation would be to compensate for your overexposure by shooting the moon and doubling and then quadrupuling your film EI (or exposure compensating -1, -2). if it's B&W, perhaps underdeveloping the negative would help (Adams used water-bath development on _Moonrise_) - -rei > I have been trying to get good moon shots with high contrast of surface detail...
