For quick and dirty metering of the moon, I think the easy mental math of the Sunny 16 rule will work very well.
However, I do have a small complaint. For whatever reason, the EXIF data on your photo is missing. Could you clue is in as to what camera you used and perhaps the telephoto lens if one was used?
As you can see, I took your complaint up with management and they gave it its due priority! Actually a bit higher than I expected! At any rate, here is the info you requested on the "Moon" shot image (not the composite version, BTW).
Finally got my camera act together for the moon. Crescent in the west at 6pm. Mounted my Sony HX300 on a tripod, set on manual with iso 250, 1/125, FL 215, auto +-1 bracket, 10s timer. Here is the result. Not bad but maybe could be focused a bit better.
