I've been watching a lot of tutorials and videos on how to capture the milky way and I've noticed a couple things that seem odd to me.
I noticed that people use a very wide aperture like f2.8 or f4 and a high ISO like 1600 and 3200.
One exposure setting was 30secs at f4 with an ISO of 3200. (He was shooting directly at the sky)
I don't understand why anyone would want to use a wide aperture?
Wouldn't you want to use a larger aperture to get everything sharp?
Was he using a small aperture to get as much light as he need so he can take the image at 30 seconds and avoid star trailing?
