This paper presents the results of the recording of stars under daylight conditions, using video cameras with a silicon photodetector array. It is shown that the SNR increases as the depth of the potential well of a pixel increases. The RT-1000DC video camera, with a potential well of capacity 170 thousand electrons, and the BCA-304 video camera, with frame summation up to an effective potential capacity of 600 thousand electrons, chosen after preliminary testing, made it possible under conditions of typical daylight turbulence of the atmosphere in the northern hemisphere of the sky to observe low-brightness stars (7m–8m) on level terrain.
