The invention relates to a field of capturing images requiring a long exposure, e.g., when photographing faint objects. The device comprises an image formation unit, an image capture unit, a primary shutter and a secondary shutter connected to at least one disturbance detector via a control unit.

Device for capturing a long exposure image

The invention relates to a field of outdoor (street) illumination, in particular, to methods of controlling light emission, as well as to a field of optical devices, in particular, to methods of reducing light pollution that affects astronomical instruments. The method of reducing impact of light of outdoor illumination devices on astronomical instruments consists in generating a light flow of illumination devices in a form of periodical pulses and in blocking the light flow directed to a light-sensitive matrix of an astronomical instrument during arrival of the light flow pulses of the outdoor illumination devices. Thus, light pollution of astronomical instruments by outdoor illumination devices is avoided.
