Very nice Bob.
Considerable difference between the two - chalk & cheese.

I was hoping we would get to see the fully processed version; the result is worth the effort. So much work to separate foreground from background, stack them separately, and then combine back again.

Stars on the bonnet, double reflection the windscreen? And that looks like the pointers reflected off the car rear window too?
