It really depends where you are. All the cities are bad, despite full cut-ff lighting having been introduced in some areas. However, it is not universal and most of the lighting is bad. However away from the cities real darkness can be enjoyed. The other problem is haze. In the southern and central parts of the Arabian peninisula this is a serious problem even in dark areas. It is there nearly all the time and one never gets a truly clear sky. Light pollution from cities makes it worse. In the north, however, the skies are much clearer, and when I have accessed naturally dark skies, the Zodiacal Light is actually quite obvious.

Could the haze be due to burning off gas in the oil fields?

Hello Brian,

Yes, it could, but it is just as likely to be caused by dust picked from the desert. It was always present in Jeddah which is well away from the oil fields. It was also observed by a member of Manchester Astronomical Society who visited the Red Sea coast of Egypt, so it pervades far and wide.

Best wishes,

Colin.
