Ebook Download | Choosing and Using a Refracting Telescope | I've been a very interested in cosmology and astronomy most of my life, but just this year got seriously interested in actually telescopes and astro-photography. I own a Newtonian, a Catadioptic, and a small Refractor. I have noticed that most of the best astrophotographs are take with refractors, so I thought I'd seriously look into getting a decent one for imaging so I bought Mr. English's book. I have to say that of all the literature I have collected on telescopes and astronomy, (I seem to have bought them all) this is, by far, the most informative, up to date, and enjoyable of them all. I have read and re-read this book and always learns something new. The author thoroughly covers the subject matter with succinct explanations of the various types of refractor design and what to expect as far as performance. If you are thinking of buying a refractor, this book is well worth reading. You can tell that the author enjoys refractors. This book is one I will keep!
