celestial latitude การใช้

For example, the north ecliptic pole has a celestial latitude of + 90?
The concentric circles the stars trace out are lines of celestial latitude, known as " declination ".
The list he compiled contains only objects found in the sky area he could observe : from the north celestial pole to a celestial latitude of about " 35.7?
Using a nautical almanac, the declination ( celestial latitude ), and the Greenwich hour angle ( celestial longitude ) are obtained of the observed object for the time of observation.
This does not match up to declination exactly zero or declination extreme value because the celestial latitude of the Sun is ( less than 1.2 arcseconds but ) not zero.
