American night hunter friends today I have to write: Happy birthday to ..... myself. By a twist of fate, I was born the day after Halloween's night of .... years ago. So today I want to give you a technological trick and give you the calculation of the Image Definition of the two most powerful thermal riflescopes for long range night shots.
Two real "monsters" for Halloween night.
FLIR Thermosight Pro PTS736 vs. ATN Thor-HD 384 9-36x
FLIR Thermosight Pro PTS736
Minimum Magnification 6x
core 320x256 pixels
FOV 3 ° x 2.5 °
ID = 3584 pixel/yard square
Lens system 75 mm
ATN Thor-HD 384 9-36x
Minimum Magnification 9x
core 384x288 pixels
FOV 3 ° x 2.4 °
ID = 5041 pixel/yard square
Lens system 100 mm
These two thermal riflescope are really 2 thermal "monsters". They have a very high ID, but I think they can only be used as a fixed stake, having a really tight FOV. Of course it is also necessary to have a thermal scanner to observe well with a wider FOV.
