Abstract: This work aims for choosing preliminary sites that can be candidates for a new astronomical observatory that will replace the Kottamia observatory. The candidate sites have been selected to be investigated after proposing a few criteria. Concerning light pollution and elevation of the sites as the main factors, we chose the candidate sites depending on the zenith sky brightness and the elevation. The night sky brightness has been measured using a Sky Quality Meter at different altitude degrees and the values of the zenith sky brightness were compared to those of different observatory sites. Our night sky brightness observations were found to be in agreement with the satellite’s data and comparable to those of dark sites, with average values of 22.07, 22.03, 21.57 and 21.58 magSQM/arcsec2. We also have obtained the Aerosol Optical Depth (AOD) and extinction coefficient due to the aerosol for the candidate sites using satellite data (Terra/MODIS).

Collison, F. M., & Poe, K. (2013). “Astronomical Tourism”: The Astronomy and Dark Sky Program at Bryce Canyon National Park. Tourism Management Perspectives, 7, 1–15.
Abstract: Astronomical tourism represents a less-studied segment of sustainable tourism, where a dark night sky is the underlying resource. This article evaluates an astronomical tourism program, in this case at a national park with dark skies for observing. Bryce Canyon National Park (BCNP) in the southwestern United States has a well-developed astronomy program to serve visitors. The program consists of solar viewing during the day, multimedia evening programs, and night-time star gazing with telescopes. Depending on the specific measure used, it appears that up to 10% of park visitors may be involved with the formal Astronomy and Dark Sky Program and/or more informal astronomy activities. BCNP appears well positioned to take advantage of the dark sky attributes of the park and to educate visitors about the importance of maintaining and/or increasing the darkness of night skies. Potential future developments in the program may serve to further increase the number of visitors to BCNP.

Abstract: This paper describes a mobile prototype and a protocol to measure light pollution based on astronomical methods. The prototype takes three all-sky images using BVR filters of the Johnson-Cousins astronomical photometric system. The stars are then identified in the images of the Hipparcos and General Catalogue of Photometric Data II astronomical catalogues, and are used as calibration sources. This method permits the measurement of night-sky brightness and facilitates an estimate of which fraction is due to the light up-scattered in the atmosphere by a wide variety of man-made sources. This is achieved by our software, which compares the sky background flux to that of many stars of known brightness. The reduced weight and dimensions of the prototype allow the user to make measurements from virtually any location. This prototype is capable of measuring the sky distribution of light pollution, and also provides an accurate estimate of the background flux at each photometric band.
