A star tracker is a portable tracking mount designed specifically for astrophotography, capable of accurately tracking the apparent motion of celestial objects across the sky. An equatorial mount, on the other hand, is a stationary or motorized mount aligned with Earth’s axis, allowing for manual or motorized tracking of celestial objects using right ascension (RA) and declination (Dec) coordinates. While both are used for imaging, star trackers are more compact, lightweight, and suitable for wide-field astrophotography, whereas equatorial mounts are versatile for various telescope setups and tracking needs.
