“Up” is the highest the centre of each pattern gets above the horizon tonight — your fist at arm's length spans about 10°. Directions are where to face when it's best placed.
Low on the horizon from Cairo
These clear the horizon but stay low, so trees and buildings may hide them: Perseus (~16°, north-eastern) · Centaurus (~10°, southern) · Gemini (~9°, north-western).
Out of reach from Cairo
At Cairo's latitude these never climb above the horizon, so you can't see them from here at any time of year: Crux, Taurus, Canis Major, Carina, Orion. To catch them, you'd need to travel toward the Southern Hemisphere.
