When I first started Astro in 2017 at the ripe young age of 57, I use to watch Trevor Jones Astro backyard channel on YouTube
He’s still presenting today but a lot of his older clips are quite good for beginners and easy to understand ( he hails from Canada )
These days it’s not a hobby for Trevor it’s a full time career
Just go to …..

Another Astrophotographer I followed starting out was Jerry Lodriguss in the US who mainly images with DSLR’s and his telescopes
Again Jerry’s e books and clips are excellent
I bought 2 of his e books

Hope the above is helpful
