What capture parameters to set for a meteor shower?

Keep in mind that the meteors “shine” for a very short time (about 1 second), so it is important not to use too long exposure times in order to capture the greatest number of meteors (even the faintest) in the images.

In addition, light pollution is a factor to be taken into account in meteor showers, since the more light pollution there is, the brighter the sky becomes during the entire capture time, which makes the meteors stand out much less and may not even be appreciated if they are too weak.

Thus, in the case of being in a fairly dark sky my recommendation is to set capture settings similar to Milky Way photography: between 15-20 seconds of exposure (so that the stars are punctual), an ISO around 3200 (or even more depending on the noise level of the camera) and close the diaphragm about ⅔ of a step.

However, in environments with a lot of light pollution it is interesting to lower the exposure time considerably more (about 8 seconds or even up to 6 seconds), raise the ISO as much as possible (depending on the camera) and also close ⅔ of step the diaphragm.

The idea is to maximize the signal of the meteors against the constant light offset of the sky.
