Astronomy imaging is using either long exposures of minutes to hours, or hundreds/thousands of images consecutively. Hence the heat buildup is cause DURING the exposure, not from LV running at an idle. Just idling in LV does cause some heat but nowhere near what is generated during an exposure where the sensor is recording the data,

so what's the difference with the work the sensor has to do by recording data and the camera processing it and sending it to a memory card or the sensor recording data and the camera processing it and sending it to the EVF????..i mean all the photo sites has to be active to work the DPAF

Im not an engineer and can't tell you exactly how it works but this is how i understand it. And again we can test for it to see if it's true. Just turn on your camera, any camera with LV, and immediately take a shot. Then leave it on for minutes or hours and take another shot.

If the noise/DR isn't noticeably different (with the same exposure ect) then we know LV doesn't build substantial heat. Have you ever heard any website that tests SNR like DPR or DXOmark mention their SNR tests are altered by how long LV has been active?

I haven't. Everybody knows many of Sony's bodies overheat in 4k video, but why not when just idling in LV? Clearly there's a difference. We have multiple reasons to believe LV itself doesn't add much heat relative to actual exposures, im just trying to prevent false info from spreading.
