Is the tower lighted at night? If not, you will probably have difficulty getting an exposure that has any detail in both the moon and the "8 ball". Several exposures merged into an HDR image may not work too well either, as the moon moves rather faster than one would expect. (though you can mask it out of all but one shot, in some HDR software). An evening exposure without the moon, followed by a shot of the moon itself, from the same position, angle, and focal length, could be merged to form a reasonably accurate rendition.
