The moon

Did you use mirror lockup? Even with a tripod and remote shutter you can get sharper still by locking the mirror. I didnt believe it till I tried!

I didn't but I'll bear it in mind

i had the same problem when i tried this with my 300mm and using a heavy crop. However i dont think i got that level of detail!

I think that a moon shot needs to be VERY under-exposed, the moon is a tiny, very bright thing against a massive dark background and lots of the pictures I took were extremely blurry until I put it at a shutter speed of about 1250 at 100 ISO
