Which distortion increases when projecting celestial coordinates onto a flat astrolabe plate at high latitudes?

💡 Explanation

When projecting onto a flat plane, azimuthal compression near the horizon increases because the projection inherently distorts angles as they approach the edge of the projection. Therefore, azimuthal compression worsens, rather than zenith crowding, equatorial stretching or meridional shearing, which manifest under differing conditions and projection methods.
