These are serious Star Charts! Not a planetarium-type app suitable for beginners, but rather a very detailed series of charts of the night sky for observers using binoculars or a telescope. Prepared by famous celestial cartographer Wil Tirion, they present the entire sky in the form of 18 charts, 16 covering the equatorial region of the sky (8 each side of the celestial equator) and one for each of the Polar Regions.

Features include:
* Stars down to sixth magnitude; double and variable stars included.
* All Messier objects, plus many NGC and IC catalogue objects.
* Auto detection of your location and presentation of the chart containing the sky directly overhead.
* Choice of positive charts (white on black, recommended to preserve night vision) or negative (black on white – easier to read and better for daytime use.)
* Charts can shown north up or south up to match your location.
* Search charts by constellation or major star name.

Basic default maps show constellation names, constellation lines and major star names only.
Extra layers can be added to reveal:
* Constellations boundaries for all 88 constellations.
* Grid lines and co-ordinates for every hour of Right Ascension and 10º of Declination.
* Star numbers and deep sky object names.

    I like these real star charts more than planetarium programs. But it's frustrating that switching to the next chart requires clicking back to the chart menu. I wish I could just swipe left or right to go to the neighbouring chart. It's worse in night mode

    Very similar to the dead tree version. Labels can be turned on and off, the color scheme can be reversed, and a red filter for dark vision can be applied. Works fine on my galaxy note 10.2

    I have several Tirion charts in dead tree format. I really would like for this to work. The splash screen and overview chart come up, but the app crashes when you tap on the overview to select an individual chart. I have a Xoom wifi and it is up-to-date.
