I'm trying very cheap and generic hardware to get into astrophotography and I'm switching between two dedicated cameras and my Galaxy s21 camera. The phone takes way better pictures as the other is a shitty lumix that offers no control and the other is a cheap entry Fuji camera I won in a bid for $15.
So far, the phone camera isn't the that bad but all three pieces of equipment have their short comings but they all share not enough exposure time.
Galaxy s21 allows a 50iso with 20 second exposure.
Fuji allows a 8 second exposure (but still has a shit time capturing light)
Lumix offers no control beyond 4 second exposure manual or 30 second exposure with an auto mode.
Is there any sort of software hack I can do to force longer exposures or is it a literal hardware limitation?
