Beautiful photos, Chas and David, and thank you for the kind words, David. My favorite shot is no. 3, Chas, while I really like Dave's first two.
Regarding the hot pixels, I can see them on my camera too. There are like 2-3 of them, but LR/ACR removes them automatically so no worries. They're normal sensor aging artifacts that I've seen in every digital camera I've owned.
As for the bokeh dust, you can even see it in older movies shot on film. It may not be visible in the lens, but these microscopic particles get magnified considerably. Sometimes they can also be on the sensor. Shoot a photo at infinity at f/16-22 and if you see the spots in exactly the same place then it's on the sensor. The funny thing is that the particles only show when shooting at wide apertures and some people call them dirty blur discs compared to normal dust that shows only at small apertures.
