Hi,
How would you keep the bags hot over a lengthy 8 hour imaging session?
There are many not too expensive dew heater solutions available from various retailers and some come up for sale regularly on IceTrades.
You can also make your own from quite simple ones to more complex ones like this one from Jaycar
