Star Atlas

From Kari Kulmala:

Charts contain over 25 000 stars to magnitude 7.5 and 346 deep sky objects including all Messier objects. All objects have visual magnitude 10.0 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. Zoom range: 0.5x3.0x. 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.
