Low on the horizon from Atacama Desert
These clear the horizon but stay low, so trees and buildings may hide them: Taurus (~6°, north-eastern) · Carina (~5°, south-eastern) · Cassiopeia (~4°, northern) · Perseus (~3°, north-eastern) · Orion (~0°, eastern).
Out of reach from Atacama Desert
At Atacama Desert's latitude these never climb above the horizon, so you can't see them from here at any time of year: Canis Major, Leo, Ursa Major, Gemini. To catch them, you'd need to travel toward the Northern Hemisphere.
