monocular for FPV test on resolution and aberrations

Short test on resolution and aberrations of a monocular for FPV sold by Banggood and several others. I used black & white figures and camera, all the colors in the b&w images are caused by the chromatic aberration of the optical system of the monocular. The real images are better than what you see from the movie. the vignetting is caused by the position of the camera that takes the movie. The images are bright enough to be seen in a sunny day even when the other eye is open and has no sun glasses.
