Sat-Sight

Latitude - λ (lambda, Greek L) - Rotation around the X axis - y on cartesian - Range: (-90,90) Longitude - φ (phi, Greek F) - Rotation around the Y axis - x on cartesian - Range: (0,360) Heading/Orientation - θ (theta, Greek T) - Range: (0, 360)

𝛼 $\alpha$ (or 𝜑 $\varphi$ ) is the signed angle between the x axis and the N axis (x-convention – it could also be defined between y and N, called y-convention).
𝛽 $\beta$ (or 𝜃 $\theta$ ) is the angle between the z axis and the Z axis.
𝛾 $\gamma$ (or 𝜓 $\psi$ ) is the signed angle between the N axis and the X axis (x-convention).

Azimuth coordinates are based on the observer's position on Earth and move with the Earth as it rotates and orbits the sun. Equatorial coordinates are independent of the observer's position and always point in the same direction in the sky. Stellarium Web Online Star Map
