Reading the sky
Panoramic charts will show the celestial equator, ecliptic, celestial tropics, poles, horizon, and cardinal directions. Ecliptic labels will distinguish twelve equal 30° tropical zodiac signs from the unequal IAU constellation spans, including Ophiuchus. Reference overlays and Greek, Mixed, and English labels are planned.
Charts will be generated using the Almanack's established calculations and reused by reference, with permanent identifiers and links back to their observing pages.
