About ClearSky

This is the complete version of ClearSky, a planetarium designed to be powerful, easy to use and very customizable. In case you don't know ClearSky, you are invited to try the free version in the corresponding page. Here is the list of the main (not all) additional features of the complete version, not present in the free version of ClearSky.

- A text mode listing all objects (more than 100 famous double and another 100 variable stars included) with different sorting options, and with a push-to function when the text mode is selected during the live view. With the device firmly holded on top of a telescope you can locate one object after another in non computerized telescopes. Only a previous alignment with one object, planet, or star not too far (30 degrees or so, depending on the accuracy of the sensors) is needed. The device can be holded in an arbitrary orientation, although in that case you will need to search in a list for the object to align to (in the first alignment).
- The main menu will show a torch option, useful as an aid when observing the night sky, or to take flat shots in astrophotography when using tablets.
- VR 3d mode (virtual reality) available, showing the live sky in 3d in SBS (side by side) mode for your VR glasses. Stars (and other objects) will appear in 3d depending of their distances!
- More complete list of the next main astronomical events (lunar-X, neomenia, among others), events of natural satellites (transits, shadows, eclipses and mutual events in Jupiter, Saturn, and Uranus moons), and artificial satellites events (transits above the observer, transits on top of the solar or lunar disks, and on the planets, and Iridium flares).
- Alerts of SN and nova events y the news option.
- High resolution textures. SDSS images can be downloaded for any position and used offline, like star fields up to magnitude 16. The details for comets will show their orbits, as well as for many double stars.
- Almost no date limitation. In conjunction with its extreme accuracy, ClearSky can be very useful in ancient arqueoastronomy, since planets are shown up to year +/- 3000, and sky can be simulated up to year +/- 200 000, including the change in the shape of the constellations due to the proper motions of the stars.
- Magnitude limits enhanced to 16! in both stars and deep sky objects. Network is required to reach magnitude 16 in stars, but only the first time a given field is downloaded.
- More bodies: recent or past SN and nova, transneptunians, radiosources. Solar spots on the Sun at any date.
- More options: custom catalogs, trajectories of bodies, J2000 coordinate system, screenshot function, field of view of your telescope on screen, polar alignment aid (see help document), sky from other
bodies, web search function solving sources not included (or present with other names) in ClearSky, current astronomical parameters (Julian day, sidereal time, date in other calendars, and many others).
- A Trivia game with more than 250 questions to test your astronomy knowledge.

This is the complete version of ClearSky, focused on being useful to amateur astronomers using telescopes. By supporting the app you will have total access to future new enhancements and features.
