You have the palm tree perfectly in focus - check that auto-focus is turned off - the palm won't be in focus with manual focus at infinity.
Three ways that I can think of to reduce the skyglow - adjust camera white balance - use software to set the white balance during processing (possibly the easiest) - or use a filter designed for light polluted areas. I have the same problem with neighbours lights.
Here is an automatic enhancement and refocus and sharp of your image, best I could do - maybe someone else can do better. In focus it would be a very nice shot. Perhaps several stacked together would be quite stunning.
Only too happy to help.
Cheers,
