Wide-field stellar photometry – the process of simultaneous comparison of apparent and catalog brightness of a large number of stars – has long been a promising method of atmospheric monitoring, as it can provide atmospheric transparency measurements with high temporal and spatial resolution without any artificial illumination of the sky which would disturb nearby optical experiments. However, only recently have we developed methods of data analysis that allow an overall uncertainty in the Vertical Aerosol Optical Depth (VAOD) better than 0.01 optical depths. Such a feat requires precise laboratory measurements of spectral and signal responses of the instruments as well as careful analysis of all systematic effects that can appear during the extraction of stellar signals from the images.
