While cooling is paramount for DS imaging, it is generally assumed it is questionable for planetary imaging.
But I noticed that if not cooled the sensor is near 15 degrees above ambient temperature (ASI 174). This delta creates turbulence in the focusing tube and a boundary layer of different diffraction on the surface of the sensor.
Is this effect relevant for planetary imaging? Should a cooled camera set in order to have the same temperature as the ambient to be considered?
