If a Northern observer sees a crescent Moon with the horns pointing right, what does a Southern observer see?

The observer in the Southern Hemisphere will see the horns pointing to the left.

The orientation of lunar phases, such as the direction the horns of a crescent Moon point, is highly dependent on the observer's location relative to the celestial equator. For observers in the Northern Hemisphere, celestial objects appear oriented in one way relative to their feet and head. When an observer moves south, the entire orientation shifts; celestial objects appear to rise and set differently relative to their body axis. Specifically, if an observer in the Northern Hemisphere sees a crescent Moon with its horns directed towards the right side of their view, an observer at a corresponding southern location viewing the same phase near the horizon will see the horns oriented toward the left, illustrating a profound, inverse shift in perspective.
