Dylan. Do you use live view to focus.
If you don't here's how I do it for faint objects
Set ISO as high as possible and your exposure time to max and set liveview to expsim. You should hopefuly get a few stars to focus on.
Otherwise focus on a bright object then mark the focus draw tube with a pencil the then you can always get close.
But this shot looks pretty good so I'll stop telling you what to do
PS don't forget to set ISO back to where you want it. Can be annoying shooting minute at high ISO
