Note that the only in-app purchases available are donations (tip jar). All functionality is included and updates are free forever - through the years, apart from the most reliable Polar Alignment app, PS Align pro has become the astronomer's swiss-army knife. Polar Scope Align will calculate the position of Polaris or σ Octantis in your Polar Scope reticle for your location (using your phone's GPS or manually), 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 help for details). It will even allow you to measure and correct a centering error of the reticle. In the settings you can select from a vast collection of reticles, one that matches your own. Pretty much every reticle in the market is supported: iOptron old & new, Astro-Physics RAPAS & PASILL, 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 / EXOS2 / Bresser, the Telrad, Rigel QuikFinder, a couple for Astrotrac / Losmandy / Kenko / Avalon, the Vixen Atlux/SX/SXD/SXP/AXD/GP/GP-DX/Polarie Polar Axis Scopes, a Konus and several Polar Finders: Tuthill, Explore Scientific 8x50, Meade 9x60, Vixen Polaris, Celestron 7x50, Carton Optical. PoleMaster help view for South Hemisphere users. Feel free to contact the developer with any questions, feature/reticle requests and any problems you have with the app. Feature list: -Accurate calculation of Polaris or Sigma Oct for any date and location, including effect of atmospheric refraction (and annual aberration, nutation). Most other apps do not perform precision calculations, so please only compare app readings to accurate sources (USNO, scientific software etc). -Use device time/date and GPS location, or manually enter your own. -Location manager with favorite locations, list of recent locations, online search and offline world database. -Full app in red-color (or alternative) night mode - tools switchable to daytime view. -Deep Space Object (DSO) Database with 13000+ objects from several catalogs (Messier, Caldwell, NGC, IC, Herschell 400, Sharpless 2). Search, apply filters, sorting, download DSS color images for all items, or get help finding them with your non-goto telescope with the Push-To function. -Over 30 calculators useful for observing and astrophotography, from eyepiece magnification and field of view, to imaging resolution and reducers. -Xasteria: World astro-weather report based on 7Timer! data -Water vapor satellite images. -List of visible ISS passes and Iridium flares. -Moon phase & lunar Calendar with solar/lunar rise/set and twilight times. -Wizard to calculate your reticle centering offset and correct or compensate for it. -Zoomable reticle view and customized routines & tools: 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. -Moon phase & lunar Calendar with solar/lunar rise/set and twilight times. -Approximate daytime / no polarscope polar alignment tool. Great for solar imaging (including eclipses). -Bubble level (using either gyro or accelerometer) and Compass heading, as well as magnetic declination reading. -GPS accuracy & elevation data. -Red/White/LED light. -Dimming slider. -iOptron, NexStar and Meade LX200 Star Lists. -Support for iPhone & iPad from iOS 7 (and iPod Touch, except compass functions). From version 3.5, an upgrade will anonymously share the iOS version, reticle and tools used (just once), so that I can focus development appropriately.
