This paper presents the results of recording stars and space objects under daytime conditions, using a video camera with a silicon photodetector array. Algorithms for summing up to 300 frames of video images and two-point correction of spatial (geometrical) noise of the array are used in real time in the camera. They made it possible to reduce temporal and spatial noise, to increase the visualization threshold of magnitude, and to observe low-brightness stars and space objects with magnitudes of 8m–10m under daytime conditions from various sites in the northern hemisphere of the sky.
