@@fromjesse Take those radiometric temperature numbers with a grain of salt wrt accuracy.....relative measures ok. Moon is white hot when I images with my 640 X LWIR.
@@pablosdog2808 Yeah, normally this thermal imager does the shutter-frame calibration every few seconds and is spot on.. But for some reason that night it was NOT doing the repeating dark frame calibration except once at startup, and so the temperature readings were going way off after a few minutes. I still need to figure out what's going on with that. However I did do some tests, and it was showing the difference in colors for temperature differences as small as about 0.2 degrees, so if there had been a cold moonlight effect I still should have seen it!
@@pablosdog2808 By the way, it would be great if you could do some videos showing your results of moon and moon light through your thermal imager and put them to youtube! The "Cold Moonlight" people are telling me that I'm the only one who has ever failed to measure moonlight to be cold...! We need more real world data!
@@fromjesse aka Flat Field Correction FFC. Try changing the temp of the camera a bit...some FFC every like ~.5 C delta or every 5 minute (on that order). I've played with many set-ups...IR radiometric cameras and t couples...and don't see the cold moon light...yet. Ken Wheeler did...with a FLIR One.
I know.. I know... So far I haven't figured out how to get the thermal imager app to record sound while recording video... This was just a quick test I threw up for you guys :D I didn't have time to dub in a sound track.
What are you using for a thermal camera? Can we go hunt big foot in my mud truck with it?
I'm using this, but if you have iphone you have to get the iphone version. www.amazon.com/gp/product/B0C23Z42KX

You need to narrate so people understand what it is you are showing us
