Many have probably tried this but I decided to dive inside
one of my DSI IIs and see how easy I could cool it.

Preliminary testing is very positive but no star shots yet.
As it's all being refined it all hangs precariously off the back
of the DSI housing until I've perfected the shape of the cold finger.

Two frames attached. First one is 5 mins after imaging when the
camera should have settled to ambient, which was 32 Deg C.

Second is half an hour later after the peltier had settled to a stable
output and the camera was cooling no more. CCD was at 4.8 deg C.

I'm not exactly sure where the DSI senses it's own CCD temp,
I have seen a post questioning where the SMD sensor is.
Maybe it's internal to the CCD....dunno, haven't read the ICX429 PDF yet.
Anyway, the CCD temps are shown here. Compared to a thermocouple/
DMM probe I had drilled into the cold finger the values are almost the
same. Probe said 5.2deg, CCD said 4.8deg.

The exact same stretch has been applied to both dark frames.
