The aperture (or more formally entrance pupil) of a telescope is larger than the human eye pupil, so collects more light, concentrating it at the exit pupil where the observer's own pupil is (usually) placed. The result is increased illuminance – stars are effectively brightened. At the same time, magnification darkens … Witryna11 mar 2024 · My naked eye observation of the 2024 eclipse had an uncanny similarity to Butler's painting of the 1932 eclipse in Figure 4, and is not surprising.
