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), 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 also from a vast collection of reticles one that matches your own - currently iOptron, Astro-Physics, Takahashi, Orion, Skywatcher, Celestron, Meade, Vixen, Bresser, Astrotrac, Losmandy, Kenko, Explore Scientific, Avalon Instruments, Konus, Tuthill, TeleVue Systems (Carton) Telrad 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.

Main features:

-Accurate Polaris / σ Oct position calculation, including atmospheric refraction, stellar aberration, nutation.
-Automatic Time/Location.
-Calculation and correction/compensation for off-center reticles.
-Supports a multitude of polar scopes: iOptron, 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, 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.
-Remember zero position on Celestron / Skywatcher / Orion etc reticles.
-Full app in red-color night mode.
-Moon phase.
-Messier, Caldwell and Bright star database.
-Download and explore DSS color images of the DSO database entries.
-6 calculators useful for observing and astrophotography.

This free version is ad-supported. You can also try the ad-free Pro version with the following extra features:

-Ability to manually enter time/date and location (including saving favorites, list of recent locations, loading from world location database, searching online).
-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 on which you can always access the polar scope).
-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.
-Switch to alternative night mode colors, or daytime mode for the tools.
-Red/White/LED light control.
-Deep Space Object Database with 13000+ objects from several catalogs (Messier, Caldwell, NGC, IC, Herschell 400, Sharpless 2). The database is searchable and fully configurable with filters, various sorting methods etc.
-Over 20 calculators useful for observing and astrophotography, from eyepiece magnification and field of view, to imaging resolution and reducers.
-World astro-weather report based on 7Timer! data.
-Water vapor satellite images.
-List of visible ISS passes and Iridium flares.
-iOptron Named Star list, Meade LX200 star list.
-Screen dimming slider.

The app is updated regularly with new features. From version 3.5, upgrades of the app to a new version will anonymously share (just once) the iOS version, reticle and tools used, so that I can focus development appropriately.
