Telescope calibration refers to the process of adjusting and fine-tuning the performance of a telescope to ensure that it produces accurate and reliable observations. This typically involves making corrections to factors such as focus, alignment, and image quality, as well as ensuring that the telescope is properly calibrated to accurately measure the intensity and position of celestial objects. Calibration is essential for obtaining precise and consistent data, especially in fields such as astronomy, astrophysics, and earth observation. Scientists and engineers use a variety of techniques and instruments to calibrate telescopes, including specialized software, reference standards, and calibration targets.
