You've got a lot of good advice. Mine is to use a much lower ISO value and much lower shutter speed. You definitely don't need to use a tripod. The IS on that lens, combined with IBIS, allows you to shoot at very long shutter speeds without camera shake. I wouldn't go too long, though, because of subject movement (the moon is moving quite fast, relative to the Earth). I would probably use 1/125-1/250. Also, bracket your exposures. And, don't expect too much using such a short lens on a subject that's a quarter of a million miles away! Given your equipment and shooting settings, I actually think your result is pretty good. I was expecting a blurry mess from your post, but it's not nearly as bad as my expectation. If you change your settings, you should be able to get a better result, but you really need a much longer lens. I've had some very good results using the RF 100-400 with 1.4 extender. That means shooting at F11, but that's OK. You'll also get better results with a fuller moon.

Alastair,  It is not often that I disagree with your posts, but here, I do.

Depending on what his image goals are, OP might get "acceptable" sharpness handheld (vs. using a tripod), but it will never be better.  If he is looking for maximum sharpness (which seemed to be the issue here), he should absolutely be using a tripod.

Going a step further, it is my experience that I get the very best results when I use a good, solid tripod, a remote release, and turn the IS off.  While I love IS for most shooting, it can have a (slightly) negative effect on critical sharpness, in a stationary setting.
