Charts contain over 25 000 stars to magnitude 7.5 and 346 deep sky objects including all Messier objects. Almost all objects have visual magnitude 10 or brighter. There is also a list of over 150 double stars.

Select a constellation, a deep sky object or a double star from the list or select a chart from an index map. You can scroll around the chart and mirror or rotate it. You can zoom in and out by pinching. You can also zoom in by double-tap and zoom out by two-finger tap

The sky is divided into 18 charts. One chart covers about 4h x 50° (polar areas: 8h x 40°). Projection is equidistant azimuthal projection.

Stars have Bayer designation (Greek letters) or Flamsteed numbers to magnitude 6.0, except some crowded places.

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.

Rubish

The program did not install. How do I get my money back

How do i use this

Is there another app that explains how to use this one? :-)

Nice star atlas

Really like these star charts, would like to see this app adapted for the iPad... Nice tool at the telescope, very handy. Would recommand it to any amateur astronomer. UPDATE... This recent update for iPhone 5 is awesome, the visual quality of the charts has improved to the point that using it on my iPad is just great! Thanks !

Uh

Meh

Good

A handy portable reference for the more serious astronomer. A big setback is that the night vision mode does not apply on the charts themselves. The NGCs are a great addition but would also like to see the Caldwell ones.

Not bad

Its cool to have something that comes complete for free. As long as you have a moderate understanding of the night sky, its great to be able to look up a certain object and be given a map centred around it. One change Id recommend for a future update would be to allow to zoom the map out further, and perhaps have something to mark the object youd selected.
