Visual Astronomy of the Deep Sky

Visual Astronomy of the Deep Sky

Want to see spiral arms of M33, M51 or M101... in a 10 inch scope? Confused about why certain not-too-dim "faint fuzzies" cannot be seen at all- even at low power under clear, dark conditions? Do you enjoy lots of graphs, charts, equations and technical writing? Then this book is for you.

Roger Nelson Clark's book gives the Serious observer of the deep sky the skills necessary to milk the most information out of every last photon of light when observing visually. He gives an extremely complete recounting of studies of the human visual system, most specifically in terms of its ability to adapt to dark conditions and perceive subtle differences in contrast, and its acuity under low-light conditions.

He asserts that there is, statistically, not a very wide range of light perception ability in the human population (amounsgt those without obvious visual disease) and that techniques he outlines in the book will help any committed student of the sky see more details.
