EOS300D megamod progress

Well, ive got the whole sheebang set up in test mode.

Dual peltier/iced water cooling installed and a 30 min dark taken.

Even with 60w of dual stage peltier and iced water cooling, I found I
could only get the cooling plate to -2 deg (30deg ambient), and the
sensor finger 11 deg at cam entry., I took a dark at 1600 ISO 30 mins,
Unscaled and scaled shown here (amp off).

Progress pics, and darks here.

Thermal isolation is a tricky thing, the mounting bracket gets cold
too, but then that cools the whole cam, so its a minor bonus, at the
expense of coolth loss unforch, much to do.
