You bet. I didn't notice but your speed was already good for a moon shot. Stop down to around an F8 / F11 and you should see improvement. A tri-pod will bring out the clarity and remember to use the built in timer. If that was hand held, that was really good!
I'm by no means a "moon" expert - just passing along what I've been told, read and practiced!
Here's one from tonight at F11 and 1/800,
+0.3EV and 300mm (sigma 100-300 F4), cropped and slight highlight adjustment in PSE-6 on tri-pod....
And here's one from December during a control burn that was still going around 8PM. This was a 30 second exposure at F/10 with +.3 EV and 50MM (Sigma 28-70, F/2.8) on tri-pod....
Good luck!!!!!
