SUMMARY
The discussion focuses on calculating the differences in Right Ascension (RA) and Declination (DEC) when observing from a specific Longitude and Latitude at sea level. It establishes that the difference in declination is solely dependent on the observer's height, while the difference in right ascension is influenced by both height and declination. The calculations require consideration of the Earth's radius, the observer's height above sea level, and the time of year and day. A rough estimate of the RA and DEC window at sea level is sought for practical applications.
