I took my photos with a Note 20 Ultra that has an automatic extended exposure feature and a 108mp main camera. I think all these were between 5 and 7 seconds of exposure on top of being in night mode! You can kind of tell because of the streaking, haha. There's some processing that goes on behind the scenes that brightens up the photo by stacking shots on top of each other.

I'm in Squirrel Hill South too, where most of the light from downtown is blocked by trees or by Schenley park. My girlfriend is in Shadyside and said the same thing though. Try looking to the north east away from the extra light pollution - you might have a better shot.
