What Is The Grid?Updated 10 months ago

Description of what the grid on the star map means

The grid is the equatorial coordinates: Right-Ascension and Declination on the celestial sphere... A bit like latitude and longitude on land.

But don't take our word for it, have a look at the link below and let someone else describe it better: https://en.m.wikipedia.org/wiki/Equatorial_coordinate_system

Hope this helps!
