How is this different from using a small aperture size?

When you reduce aperture size the depth of field increases. So for example when you use f/16 pretty much everything from a few feet to infinity is in focus.

Is that actually true? I do astrophotography through an f/10 telescope and its focus is very sensitive. I use a focuser that moves the camera 0.04 microns per step.

Not doubting you, just asking to understand. Astrophotography doesn't always behave the same as terrestrial photography
