Hi Darren
not bad considering the short exposures and the Moonlight!
There's an odd artifact in the bottom right hand quadrant that almost looks as though some stars are replicated but washe out a bit (see in the nebula) could it be a problem with stacking
Can I suggest you get and try DSS (free) I usde it and love it
cheers
