Possibly two dozen UFOs flying over at night

I looked up into the sky and saw a large cluster of objects, barely noticeable, dimmer than the light of stars. At this time, through the night vision device, I filmed the night sky, the camera took pictures through the eyepiece of the device and managed to write down the moment before the view of the sky closed the building nearby. The objects flew noiselessly and very slowly, perhaps it was a cluster of UFOs of extraterrestrial origin.
