The terminator is the boundary between lunar day and night. Low sunlight there casts shadows that can make crater rims and terrain easier to distinguish.
The Moon's angle changes with your location and the time. Telescopes may rotate or mirror the image. South-up rotates this guide by 180°; it does not simulate an instrument's mirrored view or lunar libration.
