Daaamn..
thats hellishly impressive..
Tell me though, are you sure that the camera is cooling to -35°C, or is it saying -35°C from ambient? meaning ~-8°c
Forgive me if thats a dumb question... I have no idea if it clearly states that its running at the -35 temp etc.. but thought it best to ask anyway... If you dont ask, you dont learn.
Impressive in any case thats for sure, if it is giving a -61° delta, thats incredible..
