Hmmm? Ok, it is quite deep.....but if I am honest

it looks like it has been painted with a brush and watercolour rather than being an image of the night sky

Not sure what advice to offer re the processing as I don't know what processing you used but the data looks to have been smoothed and averaged too much causing a stepped or terraced effect, if that makes sense

which doesn't look natural and the core is a bit blown.
Hope I don't sound harsh, trying to be constructive as overall it has plenty of potential
Great news about the performance of your gear though Andy, working apparatus is always a plus
