Polar Scope Align will calculate the position of Polaris or Octantis in your Polar Scope reticle for your location (using your phone's GPS or entering a location), allowing a quick and accurate polar alignment. It is one of the few programs that are accurate 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). It will even allow you to measure and correct a centering error of the reticle - very useful for polar scopes that are not easy to adjust (e.g. iOptron ZEQ25). In the settings you can also select from a collection of reticles, one that matches your own - currently iOptron, Astro-Physics, Takahashi, Orion, Skywatcher, Celestron, Meade, Vixen, Astrotrac, Losmandy, Kenko, Tuthill reticles are available. Feel free to contact the developer with any questions, feature requests, extra reticle requests and any problems you have with the app. If you like Polar Scope Align, please consider leaving a review on the app store.The Pro Watch version has all the features of Polar Scope Align Pro, with the addition of an Apple Watch app with both a graphic reticle screen and a text screen.Feature list:-Accurate calculation of Polaris or Sigma Oct for any date and location, including effect of atmospheric refraction.-Use device time/date and GPS location, or manually enter your own.-Location manager with favorite locations, online search and offline world database (cities/towns of at least 1000 population).-Supports a multitude of polar scopes: iOptron, Astro-Physics RAPAS, various versions of Takahashi EM-10/11/200/400/500, NJP, PM-1, P2-Z, the latest Orion / Skywatcher, the Classic Skywatcher / Orion / Celestron / Meade, one for Astrotrac / Losmandy / Kenko, the Tuthill Precision Polar Finder, the Meade 9x60 Polar Viewfinder and the Vixen SX/SXD/SXP/AXD/GP/GP-DX/Polarie Polar Axis Scopes.-Full app in red-color night mode.-Moon phase & Lunar calendar.-Wizard to calculate your reticle centering offset and correct or compensate for it.-Zoomable reticle view.-Alt-az alignment error display for mounts that calculate it after star alignment (e.g. iOptron iEQ45, CEM60).-Polar alignment when your scope is not in zero position (for mounts like iOptron ZEQ/CEM on which you can always access the polar scope).-Remember zero position on Celestron / Skywatcher / Orion etc reticles.-iOptron Named Star list.-Bubble level (using either gyro or accelerometer) and Compass heading.-GPS accuracy & elevation data.-Red/White/LED light.-Dimming slider.-World astro-weather report based on 7Timer! data.-iOptron Named Star list.-Supports iPhone, iPad and Apple Watch.There is also a free ad-supported version that does not allow manual entry of date/time/location and lacks features like the Apple Watch app, the zoomable reticle view, the bubble level etc.
