Moonbound
Read full descriptionHide full description
Moonbound tells you what is worth looking at on the Moon tonight. Open it and you see the sky as it really is: the Moon where it sits on tonight's pass, how high it is, which way to face, and how much of it is lit. Drag across the sky to see where it will be later on. Below that are the sights worth your time tonight, picked from the way the Moon is lit and tilted right now. Each one tells you why tonight suits it, where to find it on the disc, and what happened there. The next seven days are one tap away, so you can tell whether to go out tonight or wait for a better night. Also inside: A catalogue of 40 classic sights, from the dark seas you can pick out with binoculars to craters and valleys that need a telescope A compass that points you to the Moon A red light mode that keeps your eyes used to the dark An alert on the nights that are genuinely special, when the light falls just right on something worth seeing A camera view to help you line up a photo through your telescope All of that works without paying. Moonbound Pro adds the 14 harder sights: telescope targets, the Apollo landing sites, and the seas that only swing into view when the Moon tilts the right way. Monthly, yearly, or buy it once and keep it. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
