Description

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 even 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 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, 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.

-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.
-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.
-Access to the latest 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.

What’s New

Version 4.9

Why not help out by rating or reviewing the new version. There are never popups inside the app to ask you (annoying!), which results to less reviews than other apps. Here's what's new:
-Tweaks in polar scope instructions
-Fixed DSO DB banner behaviour.

Can’t say enough good things

This app is indispensable if you’re polar aligning and want the most accurate alignment night to night over a big range of reticle types. I tried all the similar apps I could find and liked this one so much I bought the Pro version!

Great niche

Great reference tool for quick polar alignment. Can use as is for short sessions or refine further with other tools after using this app.

Awesome polar scope must have.

Exactly as the title states....
