Here's a picture I took of the Milky Way with my phone. My telescope rig is out of commission until I get my new (used) observatory up and running. I need to install the dome rotator, but I'm waiting on a part to arrive before I can finish.
This is all I've got for now. I took this last weekend with my Pixel phone in astrophotography mode.
If you want to see my older images, I have quite a few posted on Astrobin here: https://www.astrobin.com/users/BensAstroStuff/
I think so, but I'm not sure how. I think some other phones are compatible and will 'just work' with Google's camera app. Others need some configuration with 3rd party software. I've never done it.
