High-quality equatorial mounts are designed to follow stars accurately, but even the best have limitations:
- Gear Backlash: Small gaps in gears cause slow, uneven movements.
- Polar Alignment Errors: Slight misalignments lead to drift over time.
- Atmospheric Turbulence: Air movement subtly shifts star positions.
These factors cause tracking drift that ruins long exposures. Guiding systems detect and correct these tiny errors in real time, ensuring your telescope stays locked on target for crisp, sharp images.
In short, guiding bridges the gap between mechanical tracking and the precision needed for stunning deep sky astrophotography.
