Use the app to direct it to point to what you want to image and it will automatically point at the object.
As another commenter said, you can also use the landscape mode to manually point it, but that is really meant for daylight images and won’t work well at night… but certainly play around with it just for experience.
Watch some YouTube videos and just play around and experiment. Don’t expect magic out of the box… it will take some time to get a feel for how to use the S50.
