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/
What is the dashed line of at the bottom?
That's an airplane traveling though as the exposure was happening.
I was going to guess you caught a string of star link satellites
