I recently finished reading "Astronomy for Amateurs," an 1888 book edited by John A. Westwood Oliver.
Instead of the usual fare for such things geared toward amateur astronomers, this book is geared toward VERY SERIOUS amateurs wishing to make contributions to scientific astronomy, from a time when the lines between professional astronomers and amateurs were still a bit blurred. Such efforts required specialization in a certain field and efforts which required patience, tenacity, and, OK, maybe what might be considered drudgery.
I've owned this book for several years, but hadn't read it until I discovered how reading while smoking a pipe makes me SLOW DOWN a bit, and I find myself enjoying books I wouldn't have the time or patience for sitting in my house.
I'm a long time amateur astronomer, and according to this book, I use my telescope as an expensive toy. That's fine with me, and it's made my life better. However, I do observe much like amateurs from the late 1800's... I find my targets by star hopping from paper charts instead of using GOTO technology, and enjoy looking through an eyepiece, having no desire to see objects enhanced on an led screen. I'm a dinosaur.
Maybe I didn't learn a lot from this book, but I enjoyed it, and maybe it did improve my skills and attitudes as an observer a bit. I guess I just love reading this stuff.
