### ⭐⭐⭐⭐⭐ 







  
  
    Takes the guesswork out of astrophotography
  

*by B***Y on Reviewed in the United States on December 22, 1999*

This book is really a gem.  While it covers all aspects of astrophotography, including equipment, film, etc..., its real strength and main focus is determining exposure.  Most other books I've examined are  weak on this point.  They give fairly vague rules of thumb and tell you to  bracket exposures to make sure you get a good result.  This book doesn't do  that.Gordon has developed an extremely precise system for determining  what exposure time is required for a given lens, a given aperture (f-stop),  and a given astronomical object.  I've used the system several times and it  has always produced a perfect exposure the FIRST time, with no bracketing  required (at first, I did bracket -- being a suspicious type, but the  suggested exposure was always the best of the bracketed group, so I  stopped).The easiest and best way to use the book's system is to check  with your lens manufacturer to see at what aperture it gives the best  optical performance (i.e. least chromatic aberration, least distortion, and  best resolution), then use the fx system to determine, for the magnitude of  the object you want to photograph, what the proper  exposure time is for  that aperture.If you're serious about astrophotography, and especially  if you're just starting out and don't want to learn "rules of  thumb" the hard way (by trial and lots of error), buy this book!  It'll save you lots of wasted film and missed shots.

book appears to be complete and intact, with certain passages highlighted. that's not cool. Otherwise book is good to go.
