You are not alone in taking hundreds of shots and like you say this would have been a definate no no in the olden days of film.
I tend to bracket a lot of my shots especialy in bright and contrasting conditions then at least I have a three to one chance of getting the right shot.
I like your moon and was fascinated to see that when you view it in Oz, it is upside down from the moon we see here in Blighty.
If you look at your shot carefully you will just see a small amount if chromatic aberration round the edge of the moon from about eight o'clock to eleven, this is very common in high contrast shots and the fact that you got an image hand held well, you must be steady as a rock.
I have attached a shot I took a while back showing the moon from our side of the earth - this was shot on a tripod using a timer release - there is no way I could have achieved anything hand held.
