interstellarum Deep Sky Atlas

The interstellarum Deep Sky Atlas is an innovative, practical tool to choose and find stars, star clusters, nebulae and galaxies. All objects are shown according to their actual visibility. Four main visibility classes separate out objects that can be seen through 4-, 8- and 12-inch telescopes. Within each visibility class, the objects are labeled in different type weights and using graduated shades and colors for the symbols. It is the ideal companion for amateur observers of all levels. Features include: Spiral-bound and printed in red-light friendly colors on dew-resistant paper, this full-sky atlas has a limiting magnitude of 9.5, plotting over 200,000 stars. Carefully structured to distinguish between objects visible in different size telescopes, allowing for a customized experience. Shows many rare and unusual observing catalogs in their entirety.
