I started my Astrophotography journey in late 2016 and followed Jerry Lodriguss, one of the leading DSLR astrophotographers in the US.
His Astropix site is a wealth of information and so are his ebooks which I purchased ( see link below )

As a beginner I can’t think of a better resource than Jerry’s Astropix site and books, the A to Z of Astronomy and Astrophotography.
It definitely laid a platform for me to go from beginner to intermediate to advanced.
I know you mentioned in the title “advanced astrophotographers” but if your advanced, you don’t need no book.
The above info and link is catered for transition from beginner to intermediate to advanced
My 2 cents ……
