Stunning photography there, Dennis!
And an excellent explanation of the curved locus of Uranus, Paul! I noticed that from Dennis's other post. Like Dennis I didn't expect that, so I had it on my list of things to ponder when I finished browsing posts... then I found this

It seems surprising to me though that the rate of curvature of the locus should appear to change so much so quickly as the conjunction approaches... I'm sure you're on the right track, it's just that the movement of the moon between the first and last images is not large (a few degrees only?)... hmm, just thinking out loud here really!
More mental wrestling to occur over this I feel!
