Stacking MOON

For a while, I am planning to do these simple experiments - Stacking MOON images
I tried a couple of times before, but not up to the mark.
Last night when everything is under favorable conditions clear sky, gentle wind, and the Moon at the top of the horizon, I got a chance to take a series of shoots with different capture settings.
ISO 800 f8.0 1/640 10 images
ISO 800 f14 1/640 5 images
ISO 250 f6.3 1/640 5 images
ISO 250 f9 1/250 5 images
Processed in Adobe Lightroom and after doing some crop and tweaks, finally, it turns up like this.
