For those that are curious...here's a crop around an area with contrast/details. This is 100% resolution, barring saving as a JPEG of course

When processing, I haven't "progressed" to masking regions and applying different levels of enhancement, so I look at the image and see what works well across a few carefully selected regions before picking the settings I like best.

And just keep in mind...this is 72 minutes of exposure time with a 4" apo, I'm sure it could be improved upon
