Kottamia Observatory is the largest telescope in the Middle East and North Africa. The telescope, which is located 80 km from the center of old Cairo, has a main mirror diameter of about 1.88 meters (74 inches) and weighs about 2 tons, The diameter of the dome is about 19 meters, and weighs more than 100 tons.
The Observatory was established in 1964 and it is located in the perfect place far from light pollution. But nowadays there is a new extension of Cairo called the New Governmental Capital located about 13 km form the observatory, so the north- western horizon of the observatory is fully light polluted and the north-Eastern to south- eastern horizon is at Bortle scale 3.
