Like the detail and colour saturation in your first image Ray.
Your stars look like mine, I use a bintel 200mm f/4 reflector. I have tried various fixes, new coma corrector, fixing flexure and always check collimation.
But the always come out the same.
You mention mount tracking noise, what is this?
Would appreciate if you could fill me in on this.
Cheers,
Justin.
