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 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 for details). 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, Bresser, Explore Scientific, Astrotrac, Losmandy, Kenko, Avalon Instruments, Tuthill, 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.
-Accurate calculation of Polaris or Sigma Oct for any date and location, including effect of atmospheric refraction (and annual aberration, nutation).
-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 (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 / EXOS2 / Bresser, the Telrad, a couple for Astrotrac / Losmandy / Kenko / Avalon, the Vixen SX/SXD/SXP/AXD/GP/GP-DX/Polarie Polar Axis Scopes and several Polar Finders: Tuthill, Explore Scientific 8x50, Meade 9x60, Vixen Polaris, Celestron 7x50.
-Full app in red-color night mode - tools switchable to non night mode view.
-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.
-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.
-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.
-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 25 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.
-Access to the latest water vapor satellite images.
-List of visible ISS passes and Iridium flares.
-iOptron, NexStar and Meade LX200 Star Lists.
-Support for iPhone & iPad from iOS 7.
There is also a free ad-supported version that offers the base functionality but lacks extra features.
From version 3.5, an upgrade of the app to a new version will anonymously share the iOS version, reticle and tools used, so that I can focus development appropriately.
Why not help Polar Scope Align by leaving a rating or review after trying the new version. There are no popups in the app asking you (annoying!), which unfortunately means there are not many reviews. What's new:
-iPhone X full screen support.
-Bottom bars more consistent.
-Updated instructions (mainly for Astro-Physics RAPAS).
-Fixed performance issue after closing bubble lever or day alignment.
Ratings and Reviews
I purchased the Pro version to give it a try and help me setup an Orion Atlas Pro mount. The app was surprisingly easy to use with great functionality. It can be as easy as opening it up to see what position to align your mount or dive into more detail about various objects in the sky and where they’re located. You can change the mount type being setup for a variety of brands that any backyard astronomer would be familiar with. Additionally, there’s an exceedingly huge catalog of information under the menu. Press the cog wheel and you open up the object list which was a delightful addition that justified supporting the app and purchasing the Pro version.
All in one tool box!
This makes the arduous task of setting up my EQ Mount soo much easier. This app is just packed with features. The bubble level/compass is especially useful when getting my mount roughly orientated. Love the display of date/time/location all in one shot. It has weather/observing conditions.. really this has just about everything you need. So happy I found it. Thank you for creating this!
New to Alignment
Just recently downloaded this app. Haven't yet had a clear night to use it with my new SkyGuider Pro. But I'm extremely impressed with its many features and functions. Many thanks to the author for a truly valuable app.
It just keeps getting better. Has all you need (except patience) to get a good polar alignment.
