Yeah, I only just found out about it an hour ago and just packed a whole lot of stuff to take to work tomorrow (will be a lunch-hour shoot).
Jupiter 250/3.5, two 2x TCs (so 1000mm f/14 to f/64), ND400, ND8 stacked, will that be enough? (add an extra Kenko 1.4xTC if i have to).
Also taking 70-300L (although I know it flares like crazy pointing straight at the sun), and a pinhole set (at 42mm they're f/177 pinhole, f/91 zone sieve, f/55 zone plate, plus a metre of extension tubes and bellows), and the lensbaby pinhole why not.
If I cook my 7D, i've also packed the EOS3 with a roll of 50ISO velvia.
Anyone know if that's dark enough? Or should I stop past the local camera shop on the way to work and see if they rent out ND10,000s?
