Sarah sighed, spinning her chair around. "Elias, the auto-guider is locked. We don't need manual corrections. The computer solves the spherical triangles in nanoseconds."

Latitudes and Declinations in the Southern Hemisphere must be entered as negative numbers. Check for Circumpolar Limits: If , the object never sets. If spherical astronomy problems and solutions

This is crucial for orienting long-slit spectrographs or for correcting differential atmospheric refraction (parallactic angle tells how to align a slit with the vertical or with the celestial equator). The computer solves the spherical triangles in nanoseconds
