How did you take this photo? I want to do a bit of Astro photography but not sure where to start.

I used a Sony a7iii with a Sigma DC DN 16mm lens, and took six long exposures in succession, and then stacked them in Sequator (free software), with a light-pollution reduction. But any camera with a manual mode that allows you to adjust ISO and shutter speed could work. And a cheap tripod works just fine... What equipment do you have?

How long were your exposures?

20 seconds each. The maximum length of star exposures is usually governed by the "rule of 500" so you don't get oblong stars or star trails in each frame. Divide 500 by the focal length of your lens (and use full-frame equivalent for APS-C cameras). That'll give you a good exposure time in seconds.
