註釋
The interstellarum Deep Sky Atlas heralds a new era of celestial cartography. It is an innovative, practical tool to choose and find stars, star clusters, nebulae and galaxies. Usually, deep sky objects are shown with just a standard symbol in the star charts. This atlas is different: 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 - the bolder the label or the darker the symbol, the easier it is to see the object. 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. It is the ideal companion for amateur observers of all levels.
