Excellent framing, Gary. One of my favourite sky regions to shoot, with 
or without a bright comet passing through!

I think you could stretch the contrast a bit more... There's scope to 
darken the background a little without making it a clipped black. And 
your brightest stars are not quite fully white - they're rather bright 
grey - so I suspect they were already clipped at the bright end before 
you subtracted the gradient? If you fixed that, it would make the final 
image really sparkle.
