This is an app to show the position of the Pole Star (Polaris in Northern Hemisphere, or Sigma Octantis in Southern Hemisphere) in the polar scope of all the iOptron(R) telescope/camera mounts. The app uses the best algorithm to calculate the position of Pole Star: The algorithm calculates 3D space motion of the Pole Star itself, precession, temperature and barometric pressure corrected atmospheric refraction, nutation, parallax, aberration, and etc.). NOTE: Since 2017/03/03, This app has the identical result as iOptron 8407, 8408 hand controller and iOptron Commander 5.4.

Sputnik!

Sputnik is an easy to use tool for predicting when the International Space Station will pass by your location or when an Iridium Flare will be visible in the skies above. Sputnik features:- Predictions of satellite and ISS sightings accurate to the second.- Second by second countdown to the satellite sighting.- Automatically keeps track of the correct universal time. * Sputnik is ad-supported *

Polar Scope Align Pro

Please note that the only in-app purchases available are tips. All functionality is included. The main reason for this is that while I intend to keep support for iOS 6/7 devices for as long as I am allowed, even for very few users, it adds an overhead so I should make sure it is really needed.

iFlares

Iridium flares are phenomenon caused by the polished antennas of the Iridium communication satellites reflecting sunlight onto the Earth below and appearing as a brief, bright flare. iFlares calculates the occurrences of Iridium satellite flares for your current position (or any other location on earth). That way your Iridium flares achievements are not only automatically synchronized between your different devices, you also can compare them with your Game Center friends.- Calculating Iridium flares directly on the device (no active Internet connection needed)- Visual navigation mode for directions- Audio countdown when watching flares- Add your own favorite locations- Multiple time windows- Many additional information on the Iridium satellites and the calculated flares- Reminders for upcoming flares- Keeps record of all seen Iridium flares and automatically synchronizes the achievements to Game Center.- Universal app for iPhone, iPad and iPod touch

Polar Scope Align

Polar Scope Align will calculate the position of Polaris or Octantis in your Polar Scope reticle for your location (using your phones GPS), allowing a quick and accurate polar alignment. It is one of the few programs that are accurate even in lower latitudes by correcting for atmospheric refraction (so expect results to agree only with precise software and not most simplistic polar align apps - see the Accuracy section in the website). The main reason for this is that while I intend to keep support for iOS 6/7 devices for as long as I am allowed, even for very few users, it adds an overhead so I should make sure it is really needed.
