Listing more than 500 sky targets, both near and far, in 187
challenges, this observing guide will test novice astronomers and
advanced veterans alike. Its unique mix of Solar System and
deep-sky targets will have observers hunting for the Apollo lunar
landing sites, searching for satellites orbiting the outermost
planets, and exploring hundreds of star clusters, nebulae, distant
galaxies, and quasars. Each target object is accompanied by a
rating indicating how difficult the object is to find, an in-depth
visual description, an illustration showing how the object
realistically looks, and a detailed finder chart to help you find
each challenge quickly and effectively. The guide introduces
objects often overlooked in other observing guides and features
targets visible in a variety of conditions, from the inner city to
the dark countryside. Challenges are provided for the naked eye,
through binoculars and the largest backyard telescopes.
