Night Sky Observer's Guide

These three volumes are an observer's handbook designed to help the observer at the telescope learn to see more intelligently what can be ascertained at the telescope.  It provides training in seeing, in how to tease out the nearly indiscernible details of practically every deep sky object that is within the reach of larger amateur telescopes.  In its emphasis on appreciating elusive visual detail, it complements Burnham's Celestial Handbook.  In its emphasis on the art of seeing rather than astrophysics, it complements Annals of the Deep Sky.  

Volumes 1 and 2 cover the northern constellations, in order of the seasons; volume 3 surveys the southern constellations.
