Congratulations Rod. Your pics are amazing! Much success to you.
FWIW, my friend, who is an avid astrophotographer, runs a site Brahmand [1] that captures breathtaking pics of the dark sky, with notes on how he took the pics.
Awesome stuff: https://www.brahmand.me/photo-gallery/

*Brahmand in Sanskrit means the universe
Wow. Stunning photos. Thanks.
