Thanks

I did take I think around 10 or 30x 30second subs of the core during this imaging session. I haven’t done anything with them yet lol.
The whole layer blending thing is something I need to sit down and learn.
Your advice is spot on though and I may have even over done it at 30seconds.
I will sit down at some point soon and re-do this entire image using a few new techniques and try and mask in the core
Ps. I am now about to frantically google what “14 stops” means
