Used the Tamron 90 + 68mm Kenko tubes with a diffused SB800 on a bracket. Made a blue with the flash head placement but I'll correct that for the next batch All 8-11 image focus stacks.
Iso 500? 1/8000?? Was there a high speed car somewhere in that shot that I missed? Or were you suffering from severe camera shake from the gale force winds that day? (please excuse any spelling errors folks )
