    Unsure, but it also outputs a time lapse at the same time where you can see the stars moving - I’d guess this is a by-product of the process (also cool that you can see some slight cloud movement which I didn’t know was there before)

      Yeah this is generally how low light and HDR camera modes work - by taking multiple photos and then using a technique called “Stacking” to average out noise and improve signal (useful light).

      You can also just take 20-30 second exposures if your phone has a “pro” camera mode, then do the rest of the stacking with other tools. The astro mode simply does everything for you, but you get less control over the processing.
