Why is the telescope adjusted for a distant object?

A telescope is adjusted for a distant object to ensure that the light from that object is focused accurately onto the eyepiece or camera sensor, allowing for a clear and sharp image. This adjustment involves aligning the optical components, such as the lenses or mirrors, to compensate for the light's path as it travels great distances. Proper alignment minimizes distortions and maximizes resolution, enabling astronomers to observe fine details in celestial objects. Additionally, adjustments account for factors like atmospheric conditions that can affect clarity.
