This is my second attempt of ground-based thermal imaging.
The Thermal Cam is now closer to the second mirror positioned
and I used an extension cable to interface with the iPad.
Thermal imaging with a telescope is only possible with Newton - type telescopes,
because thermal wavelengths can reflect on metallic surfaces
but would not pass regular optical lenses etc.
The Seek thermal cam is therefore directly exposed to the second mirror of the Dobson telescope.
The images show the apparent temperature in celsius, not corrected by the atmospheric
spectral correction factor.
This would require a rather complicated process of calibration and test equipment.
Moon surface temperature range is 200° - 300° Kelvin
Thermal cam resolution : 207 x 156 pixel
pixel size : 12 um
wavelengths between. : 7.2 and 13 microns
P.S. here a reference to a detailed scientific paper on ground-based thermal imaging:
