I'd recommend a book I've been reading: A Manual of Advanced Celestial Photography, Brad D. Wallis, Robert W. Provin .
Amazon has a used one for $1.57 , a very interesting book, it also shows how during decades astronomy advanced by recording objects that could not be seen by human eye.
I bought a slightly better condition, I dislike mold.
$5.99
Thanks, but I usually use ABE Books, I find them cheaper with a bigger range.
I may even have this book already, but I can't find it after my move.
The 'hinge' is so simple and now that I can actually see the stars, I will. I was inside Chicago for a long time. Now rural.
Thanks again!
