This is actually my first astrophoto, I shot it with a 50mm f/1.8 lens wide open, the exposure time was 30 secs, and I think trails are a little noticeable.
I made this from a beach that I "thought" it wasn´t too much light polluted but apparently it was. I believe its light pollution (not sure) also I think there´s some vignetting because I shot at f/1.8. Sorry about the size and poor resolution but I ask a friend of my to scan it (its a print). I still dont have a scanner.
The same image with colors inverted, I think you can see better the light pollution and vignetting
