Polar Scope Align Pro

By Dimitrios Kechagias

This app is only available on the App Store for iOS devices.

Description

Please note that the only in-app purchases available are tips. All functionality is included.

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, 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.

Feature list:

-Accurate calculation of Polaris or Sigma Oct for any date and location, including effect of atmospheric refraction (and stellar aberration).
-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, the Telrad, a couple for Astrotrac / Losmandy / Kenko / Avalon, the Tuthill Precision Polar Finder, the Meade 9x60 Polar Viewfinder and the Vixen Polaris and SX/SXD/SXP/AXD/GP/GP-DX/Polarie Polar Axis Scopes.
-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.
-Red/White/LED light.
-Dimming slider.
-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.
-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 6.

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. 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.

What's New in Version 3.6

Polar Scope Align never nags you with popups about a rating/review, so it doesn't usually get many ratings, but some users did take the time to leave a rating/review and I thank them. If you can also rate again after you try a new version, that would be great, as star ratings get reset and Polar Scope Align gets updated too often to keep a rating (there is a link in the settings page if it helps).

What's new:
-The "Point To The Sky" sort function in DSO Database now shows icons with the type of objects when showing a list of the nearest objects to where you are pointing.
-When your device does not give the app access to the true north heading, you will be warned and the app will try to calculate true north from the magnetic north.
-DSO DB list view has clearer font.
-Fixed slider/switch issue on iOS 6.

Customer Reviews

My most valuable app for astrophotography!

I use this app every single time I shoot astrophotos on my iOptron CEM25, and it aligns the mount perfectly every time! Or has a whole slew of different polar scope types, as well as practically any calculators I might need. Plus Clear Sky Charts and other weather forecasts are integrated into the app now too! The app has become more and more valuable with the update, and I'm very appreciative that the developer keeps improving it! Definitely worth the price!

Seriously one of the best apps I have

I use this to align my Skywatcher Adventurer in a few minutes. One of the new features is the Daytime / No Polarscope Alignment. I use this at night as well to quickly get the wedge close. Then I use the normal mode to fine tune.

Don't even bother

Don't even bother trying other apps to align your polar scope. This app puts everything in reach and gives me so many additional features. Essential part of my astrophotography toolkit.
