The best Infrared spotting setups 

Experience shows that the best IR setups are the ones where you have full control of the zooming lens: zoom, focus and iris opening, lens with automatic iris suffer exactly the same shortcomings that cameras with automatic focus: the results are not optimal for tracking small objects in the atmosphere with all kind of different objects and lighting conditions in the field of view.

Experience also shows that in these manual lens the iris opening should be kept to a minimum allowing very little light to reach the camera sensor, in that way contrast and "depth of focus" are increased: more range for objects to be in focus and that is critical for detection.
