iObserve

Observe the sky like a pro... now on iPad!

iObserve brings your preparation of astronomical observations to a much higher level. It gathers all the information you need when observing the sky with small and big telescopes, and let you manipulate your nights and targets. It has been built from the ground up by a former ESO support astronomer in Chile.

iObserve on iPad brings almost everything its sister app has on desktop (available in the Mac AppStore), in the beautiful touch canvas of the iPad.

What others have said about this app:

Grade A (5 Stars): "I do a lot astronomy thru remote (but world class) ground to space observatories, where the sky in real time looks very different than from my local observatory. This app is a Grace of Gott when it comes to figuring out what DSO is best to target for what night at which geolocation at which time to get best use of the observation slots available... and yes, it also works great for my backyard... This is a breakthrough astronomy application, it isn't as sexy looking as other AstroApps, but what it does is in terms of being an "easy button" in you getting the astroexploration of your hearts desire done is at a level by itself."

iObserve allows you to:

• Easily import any known in SIMBAD or not-yet known object, browse the Exoplanets catalogue or download the latest JPL ephemeris of any known comet and asteroid. All object parameters, properties and references will automatically be kept up-to-date.

• Draw and track multiple colored airmass curves for about 100 builtin observatories on Earth, and get the objects sorted according to the best observing time,

• Draw multiple star tracks with builtin or custom horizon masks, and follow targets across the sky, within customisable night boundaries,

• Find automatically the closest standard stars among 21 000 optical and near-infrared (spectro)photometric or telluric stars stored in 6 different catalogues,

• Download the SDSS, DSS and 2MASS finding charts in multiple photometric bands and with numerous options,

• See the Moon's airmass curve, along with its age, coordinates and illumination fraction, and its minimum separation to any object,

• Easily convert fluxes and magnitudes between different units, et get immediate extrapolations in every bands of the Johnson, Cousins, Strömgren, TYCHO2, SDSS and 2MASS systems,

• Easily convert object coordinates between equatorial, celestal (sidereal) and galactic systems, for any epoch in various units,

• Convert times and dates, and see how the Earth shadow is placed on the world map, relative to your position and that of your observatories,

• Convert small and large distances, and, like all other conversions, save it for future reference.

Moreover, iObserve lets you create new observatories – being a remote location, a professional observatory or simply your backyard – using GPS location if you like. You will then be able to use it like any other builtin observatory.

iObserve also provides its famous times bar with Local Time, UTC, (Modified) Julian Date and the Local Mean Sidereal Time for all its observatories.

更新履歴
iObserve for iPad is now better than ever! This update drops the support for iOS6 and iOS7, as many of you have already migrated to iOS8. And it makes the life of the developer a lot easier. Here comes the list of improvements and fixes:

• Updated for iOS8 (finally), but also dropped the support of iOS6 and iOS7.
• Added the AAVSO finding charts.
• Fixed various issues when changing the input values in the Fluxes converter.
• Fixed the crash of Zenithal grid and the images of the slider, on Startrack plots.
• Fixed some editing issues for websites.
• Improved the printing of all Finding Charts together.
• Fixed the wrong separation angle of standard stars.
• Fixed the wrong rows in the 'infos' table section of standard stars.
• Improved the welcome process (the first time one launches the app).
• Fixed an issue on the New Small Body sheet, when selecting the last row of a multiple-solution lookup (detected on OSX).
• Improved the parsing of JPL solutions (detected on OSX).
• Fixed the webservice URL for exoplanets.
• Updated the builtin exoplanet catalogue (but it remains of course possible to update it directly from the app).
• Various small UI enhancements, and stability enhancements.
