WebMay 3, 2024 · The gold standard in measuring the distance to a star is stellar parallax. If you can't do parallax, then distance-independent properties of stars sometimes serve as clues to distance. Measuring brightness is generally the easy one. CCD's are often used to measure apparent brightnesses. WebJul 19, 2024 · Aperture Aperture is very similar to the “pupil” of your camera lens. Just like the pupil in your eye, it can open or shrink to change the amount of light that passes through. This is how the aperture blades look on a typical lens: Aperture blades inside a lens. Your lens probably looks something like this.
