What is this app? A guide to exploring interesting stars and deep-sky objects.
How to use it? Select a constellation and navigate through its different objects. When you exit, the last object viewed will be saved so you can continue during your next observing session. It also allows you to mark objects as viewed, copy the object name (to transfer it to a star chart or telescope control program), and make custom annotations.
