Simplified high quality All Sky Camera.

OK I thought - back to having the passive cooler below everything else and use an axial fan with suitable ducting. To start with, from the bottom :- Passive cooler Peltier TEC (if wanted) 40mm x 40mm x 11mm heatsink with fins upwards Axial fan 40mm x 40mm x 10mm blowing upwards, drawing air through the fins of the heatsink Not shown yet - air duct to concentrate cooling air into centre of sensor PCB Added air duct on top of fan and an inner casing to contain the cooler air and return it to the heatsink. Main outer casi -

I'm concentrating on the Raspberry Pi High Quality Camera for now - much easier to use. CAD model of camera with just enough detail to avoid parts interfering. The camera tripod mounting bracket seems attached with screws so may be removable. Had several thoughts about possible cooling methods. The underside if the sensor PCB has lots of components so conduction cooling even with thermal paste is not viable. A simple chamber with camera at the top and cooler at the bottom - but convection is the wrong way - cooled air doesn't rise!! Air could b -

I took the innards out of the ASI178MC and separated the boards to show the underside of the sensor board also took a photo with just the top off. This camera has already been saved form the scrap heap from when the USB socket got broken and I soldered wires onto the board. Sensor and main boards opened up showing the back of the sensor through that tiny hole in the sensor board. Inside of the case. It can be seen that there's a small rectangular hole in the sensor board showing the back of the sensor. So if opened up air could be blown o
