Description	The paper deals with long-term measuring instruments for light data collected under the night sky. The point of such measurements is to quantify the obtrusive light and compare the level of the obtrusive light in populated industrial areas and out of them. For long-term measurements of low level illuminances (about 10-2 1x) and luminances (about 10-3 cd/m2) should be applied not only the measuring instruments with high sensitivity, but also completely independent instruments with the ability to save the measured data. For low level illuminances measuring is described luxmeter satisfying the above requirements. The issue of measuring the low luminances is solved by digital photographs. In this paper is also showed the astronomical camera with cooled CCD chip, which is able to minimize the thermal noise. The last described device for long-term measuring of the night sky is astronomical instrument (Sky quality meter), which evaluates the luminances of the night sky.
