I've got a 4x5 and an 8x10 set up for long trail exposures, but I confess I'm going to rely on d*g*t*l for shorter "portraits" of the eclipsed moon. The 8x10 is loaded with x-ray film, oddly enough---it's the fastest film I have in the size, but it's green-sensitive, so I expect the lunar trail will basically disappear during totality.
We have reasonable hours out here on the West Coast, but even so, I'm going to need to set an alarm for 2:30 to get up and close the shutters.
