An essential tool for every astronomer. The star atlas that makes it really easy to pick the best objects, make your own observation list and use it when you are outside + free Apple Watch app!

Ad Astra contains detailed maps of all 88 constellations, descriptions of more than 1200 of objects: star clusters, planetary nebulae, galaxies, double stars and variable stars. All within reach of amateur telescopes and in a lot of cases, also viewable in binoculars.

If you like an object, just press the + sign next to it to add to your personal observation list. When you go outside at night, use the large maps in the special red night vision mode to find the object and start observing.

Ad Astra covers both the northern and southern skies. And supports both your iPhone and iPad, you only have to pay once to use Ad Astra on both devices!

Ad astra is made for everyone who likes to explore the heavens with a reliable tool. If you are done with planetarium apps and up for some real star gazing, this is your way to go deeper.

Ad Astra has been built upon open Astronomical data. It features deep sky objects up until visual magnitude 12. What do you want to see tonight? Start now.

Great app if you want to learn the night sky. Better than any book atlas I own.

Ad Astra - A very useful app for the backyard astronomer *****

Just discovered this very useful app. It brings all the constellations at the tip of your finger. Very nice when observing at the telescope. There are plenty of useful astronomical apps - planétariums, planning apps, etc. but very few atlases and this one is very nicely designed. The free app convinced me to get the Pro version... I suggest you give it a try...

Reminds me of my old Norton Star atlas, great observing notes and observation list. If you want a good guide to the night sky this is what you want.
