Probably the crappiest image on this forum, but also the most convoluted solar radiation image?
I spent some time watching little owls hunting worms on a local cricket pitch using a thermal scope, would never have known they were there otherwise. Very good for finding warm critters at night. So the background image is reradiated warmth from the daytime sun and the owl and dog glow from the food they’ve eaten that eventually comes back to photosynthesis from the sun…..

Ooooh Aoooh Peter.
Certainly is an unusual capture you have shown.

Different but somewhat interesting what IR scopes/cameras can record.

I must try my own one to see what can be captured (including my irregular Fox intruders).

This is thermal as in 10micron wavelength heat radiation, not 1.5micron near infrared. Camera resolutions are much lower as the pixels are much more complex to detect the tiny temperature differences: I’ve sat on the fence waiting for “good enough” to become “cheap enough”. The time has come and I’m now able to spy on the critters that come out after dark.
Thanks Alex!
