I'm going in for cataract surgery, but I think photo quality is being affected by technique or equipment.
Suggestions please.
As others have said use live view with focus peaking zoomed in and focus manually. The moon is travelling through space at over 2200 miles per hour so you need a reasonably fast shutter speed even at this relative distance also use spot metering. Also use either a wireless shutter release or a wired one. after focusing you shouldn't need to refocus during shots unless you missed on the first try. After manual focusing with focus peaking and before triggering the shutter let the camera and tripod settle down for a few seconds to reduce oscillation induced by focusing.
Here is a shot taken in 2014 with my K-50 if you care to check the EXIF just click on the image and go to Flickr to look at the camera setting in the EXIF file. This was taken with an older Sigma 70-300mm F4-5.6 APO DG Macro zoom not the sharpest out there for sure.
