Near all-sky imaging photometry was performed from a boat on the Gulf of Aqaba to measure the night sky brightness in a coastal environment. The boat was not anchored, and therefore drifted and rocked. The camera was mounted on a tripod without any inertia/motion stabilization. A commercial digital single lens reflex (DSLR) camera and fisheye lens were used with ISO setting of 6400, with the exposure time varied between 0.5 s and 5 s. We find that despite movement of the vessel the measurements…

Beyond All-Sky: Assessing Ecological Light Pollution Using Multi-Spectral Full-Sphere Fisheye Lens Imaging
The first step to fill the gap in a widely-applicable measurement method for nocturnal light providing spatially resolved full-spectrum radiance over the full solid angle is explained, by using a commercial digital camera with a fisheye lens to acquire vertical plane multi-spectral (RGB) images covering the fullSolid angle.
Methods for Assessment and Monitoring of Light Pollution around Ecologically Sensitive Sites
The challenge of quantifying light pollution threats to ecologically-sensitive sites in the context of efforts to conserve natural nighttime darkness is described, the current state of the art in detection and imaging technology as applied to this realm is assessed, and future prospects for imaging approaches are considered to provide substantial support for darkness conservation initiatives around the world.

Characterizing the zenithal night sky brightness in large territories: how many samples per square kilometre are needed?
A recurring question arises when trying to characterize, by means of measurements or theoretical calculations, the zenithal night sky brightness throughout a large territory: how many samples per


Light pollution and astronomy
All astronomical observations are essentially an observation of contrast. Any stray light causes a veil, reducing all contrasts. Sky glow is disability glare. This hold for all sources. Diffraction
Measuring and modelling light pollution at the Zselic Starry Sky Park
One of the first 'International Dark-sky Parks' in Europe was established at the Zselic Landscape Protection Area in Hungary. A special monitoring program has been carrying on to survey the quality
