A beautiful reference tool!

This is a direct and easy atlas of the Constellations and Messier objects which allows the observer to quickly locate them. It is perfect for guiding anyone while using a telescope, (which I do frequently). The colours used in the maps are distinct but not garish, thereby minimizing the impact on night vision. This is the best map set of its kind I have seen and I happily recommend this App very highly to anyone, whether they are just starting out in Astronomy and want to learn the constellations, or they are seasoned observers and want to observe the Messiers through their binoculars or telescopes.
