Anyone who uses a telescope needs a sky atlas as a guide to finding star clusters, nebulae, galaxies, double stars, etc. The problem is that most sky atlases assume the user has a least a 6-inch telescope, whereas the vast majority of beginners start with small 2.5 inch to 4 inch telescopes. Beginners may meet with frustration attemtping to view objects too faint for their equipment. This book fills the literature vacuum for users of telescopes in this size range.
