Hmmm, I am still learning but can give you my limited advice for what its worth..............
Several points.
A full moon is always a bit tricky as the sun shines directly onto it, thus reducing shadow and detail for most of the area.
I found that despite the camera being on a tripod, there was still camera shake as the shutter opened and closed. Have really got to reduce this shake to zero
Stacking using Registax 6 helped considerably. I use maybe 20 shots taken on the machine gun button (shutter mode) and stacked those. There are several stacking programmes around, many are free. Registax works well. for me anyway.
Usual things about IBIS being shut off when on a tripod etc.
I have actually had some reasonable shots handheld, using Olympus Em1 with a Pany 400mm lens, but they are not consistent alas as I am a bit shaky these days alas.
Your shot is actually quite good, but as you see from Roberts offering there is much more detail to be had.
That's my 2p worth, there are some very good astro photographers on here who will give more advice, good luck and keep trying. The moon is a bit like a robin, difficult to resist....
