It appears that many texts on astrophotography and telescopes for amateurs tend to avoid mathematical formulas, as such, they are of little use to do some practical calculations.
What I am interested in is:
Magnification
Image scale
Focal length
Focal plane and sensor plane! (CCDs!)
Focal-ratio and its physical significance
Field of view
Resolution
Diffraction limit?
etc
Extra: find focal length of telescope from radius of curvature?...
Essentially, a book that covers all practical calculations one can find.
Do you know of any such book? I have the eerie feeling that a full-blown geometrical optics textbook is required, but then one still need to read about lens design... And another for mirrors and telescope. Indeed mirrors! Do they call that mirror design?
Or is basic knowledge just enough for practical applications?
A relevant book is:
Physics of Digital Photography, Andy Rowlands (actually, 2nd ed is out)
Judging from the first chapter (freely available on publisher website), it is indeed fairly technical. Though, it appears to be insufficient as a standalone text. Readers it seems are referred to the more than 5 textbooks listed at the reference (I'm not sure about 2nd ed though, plus I have to look at the ensuing chapters.)
Thanks in advance!
