could you please share the exposition values?
I've tried many moon shots and nothing like your 1st shot!
If you're familar with the SUNNY 16 rule of thumb (shutter speed 1/ISO sec at f/16 in bright sunlight), try "MOON 11". The Moon is actually very bright being directly illuminated by the Sun. A sturdy tripod, mirror lock and a remote shutter release or timer release can also help a lot.
