interstellarum Deep-Sky-Atlas will show you all deep sky objects according to their actual telescopic visibility. With a single glance, you can see whether any object is visible with 4-, 8-, or 12-inch telescopes.

Sure! With its revolutionary design, interstellarum Deep-Sky-Atlas will help you to pick out those objects that you actually can see! In most other atlases, up to 50% of the objects shown cannot be seen with a moderate to large telescope. This atlas will only present you with the visible ones - frustration will be avoided.

Of course! The visibility of deep sky objects in your telescope can be estimated quite easily with the atlas. If you want to know exactly, we suggest using Eye & Telescope software, which allows detailed calculation for any given telescope and sky conditions.

Your atlas is not really aimed at visual observers. As the object database of your atlas is not based on the actual visibility of objects shown, there are many targets way beyond the limits of medium large telescopes. Most atlases boast very large numbers of deep sky objects, but you won't be able to see a large number of them. interstellarum Deep Sky Atlas will not only show you those objects that you can actually see, but also all of them! All popular atlases miss several thousand objects that are within reach of moderate large telescopes - this atlas does not!
