Light gathering

Light gathering refers to the ability of an optical instrument, like a telescope or camera, to collect and focus light from distant objects. Instruments with larger apertures, such as wider lenses or mirrors, can capture more light, making faint objects brighter and clearer. This is crucial for observing celestial bodies or capturing detailed images in low light conditions. Essentially, better light gathering improves visibility and detail in images, enhancing our ability to explore and understand the universe.
