I'm working on MkII, Rev 1 now. Ordered another TEC because I've reinstated the AS! 120 setup, 20* plus delta under test.
The revision is an internal wrap around aluminium plate for the TEC to connect to. Goes over the top and down under the camera so a lot of area and I've modified the Mk I external foam insulation to fit over the rear of the plastic enclosure. The front is still internally insulated.
I'll post a few pix up when I put it together after the TEC arrives.
Long term I need a power adapter for the 450D so I don't have to open it up to change batteries. It lasts a full night easily but I could insulate if better if I didn't have to make it accessible. Moisture control will be by silica bags inside the enclosure. If I can get a good 10-15* delta I'll be happy.
