Might not be exactly what you're wanting, but I took this from my hotel room in Tampa on the 4th of July.
wondered about this since in my personal experience my 50mm( 1.8) is tack sharp at really small aps( like above f18) and not great in the 11-14 range. now that it's been recalibrated my 70-200 f4 really is pretty good throughout the whole range but probably a little less so above f14 or so if i get really nit picky about it.( like i commonly amI did a bit more reading on diffraction, and I was only sort of correct in what I said before about APS-C and f/16. Turns out that's just a general rule and it depends on the lens. Consumer quality lenses that perform best when stopped down will actually perform better at very small apertures than will high end lenses that are very good wide-open. So a cheaper lens that is best at f/8 might not start seeing diffraction effects until f/16, but a pro lens that is best at f/4 might only go to f/8 before sharpness starts to drop.

Great shot Tom! Is that Spectromagic? What a unique way to capture it.
ETA: I just checked out your Flickr page. Was that 103 seconds for the exposure? I can't believe you've only been doing this for a year. I have always admired all your night shots. They are phenomenal! We just planned our next trip for this December and I can only hope to get some great night shots like you have gotten. Kudos!
