The Right Ascension (RA) axis is aligned with Earth's rotational axis and points toward the celestial pole. It rotates to counter Earth’s spin, allowing the telescope to track stars smoothly.
The Declination (DEC) axis is perpendicular to the RA axis and moves the telescope north or south in the sky, letting you point at any celestial object.
Together, these two axes let your telescope follow the sky’s coordinate system precisely, making equatorial mounts ideal for astronomy and astrophotography.
