Actually, there maybe one or two that particular shape, probably a good place to start heat probing. I presume it's a temp sensor IC you've researched.

There's an 8-pin SOT under the CCD, but that seems a bit fancy for a temp sensor.

I've left it running on the scope in the obs as a smoke test for the TEC circuitry, the Envisage CCD temp reading is now down to +21.5, and the finger thermistor is -1.2C! Both obviously decreasing as ambient goes down (6pm).

I'll re-open it tomorrow and follow up your suggestions.

Cheers,
