You can do a Photoshop correction by lassoing that area, feathering it 20 pixels, duplicate layer, set it to darken mode then filters/other/offset and play with the vertical and horizontal numbers (they may need to be - numbers ie -1) until it looks better. You may need to boost slightly with curves as sometimes it dims the stars. Fine adjustment by opacity of the slider or edit/fade.
If you're not comfortable with the above I am happy to do it for you. It'd take me 2.5 minutes (I'll time myself!).

Thanks again guys!
Greg, very generous offer mate, thanks you! I will see if I have time to stuff around with images past or move on to the next one. I will certainly be practicing this out there at night to hone the focus, guiding etc. I'd rather perfect it in-camera than try to fix in post if you know what I mean.
Your methods certainly sound like a skill...(that I probably don't have)...either that or my software might not do it...PSE6...
