Description

Note: 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 more 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, 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, requests or any problems with the app. If you like Polar Scope Align, please consider leaving a review on the app store.

The Pro Watch version has all the features of Polar Scope Align Pro, with the addition of an Apple Watch app that offers:
-Graphic & Text display of polar alignment.
-Weather view.
-Bubble level.
-Day alignment.
-Moon phase/altitude.
-Moon/Sun rise/set/twilight end times.

App feature list:

-Accurate calculation of Polaris or Sigma Oct for any date and location, including effect of atmospheric refraction (and stellar 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 & 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.
-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.
-iOptron Named Star list.
-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.
-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.
-Supports iPhone, iPad and Apple Watch.

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:
-Updated Meteoblue to point to their new website (their website now requires iOS 9+)
-Tweaks in polar scope instructions

A Great Bargain!!

There are so many “ apps within this app” that it could replace several other apps I have on my phone. The Polaris finder is accurate and easy to use and the Moon calendar and DSO calendar make planning observing runs easier.

Best polar alignment tool after the polar scope itself!

Do you think your polar alignment scope is enough to align your mount for astroimaging? Think twice! This little app takes into account precession, refraction, aberration and a ton of other phenomena to achieve exceptional precision.

Excellent app

This is one App you want before observing while setting up your scope. Helps accurately align to the celestial pole, and has useful lists of objects as well.
Highly recommended.
