Both seeing and transparency are essential factors to consider when planning a stargazing session, as they can significantly affect the quality of the viewing experience. Poor seeing conditions can limit the amount of magnification used during stargazing. Seeing refers to the atmosphere's stability, which can cause celestial objects to appear wavy or distorted. On the other hand, transparency refers to how clear the sky is and how much light can pass through it. Poor transparency can be caused by factors such as light pollution, haze, or moisture in the air.
