PolarFinder Pro v2.5.4
Raffaele LunariAbout this app
Developer Description
Application required to perform precise night polar alignment.
In the settings you can choose to exclude the GPS and enter the customized coordinates and / or even a particular date and time in order to know the exact position of the Polaris (northern hemisphere) or Sigma Octantis (southern hemisphere) for a certain place.
This feature is also useful to know the peak of the polar for a specific place directly in the field without having to resort to third applications.
Once the position has been calculated, the polar image will be shown exactly as it should be set in the polar telescope, remembering that it inverts the images (the app also allows real vision).
ATTENTION: To use this app you need to see the Polar star and have a polar scope.
Main features of the app:
1. Possibility to manually enter coordinates,
date and time excluding
the gps;
2. Various reticles available:
- PolarFinder;
- Skywatcher (old and new);
- Ioptron;
- Bresser;
- Astro-Physics;
- Takahashi;
3. Works in both hemispheres;
4. Possibility of activating/deactivating the
view through the polar telescope (inverts
the images);
5. Possibility of activating/deactivating the "Full Screen" view;
6. Possibility of activating/deactivating the "Super Dark" view;
7. Position of the Polaris or of the Octant very
accurate thanks to the
calculation of the phenomenon of the
Precession;
8. Altimeter;
9. Very accurate help
PLEASE NOTE:
This app unlike most apps of its kind, takes into account the phenomenon of the Earth's Precession.
The Earth has a rather complex movement, one of them is called the Precession where the rotational axis of Earths slowly changes its orientation and the celestial poles are slowly changing with it. This movement is rather small, around 26,000 years per revolution, but in time it changes the apparent position of celestial objects. As the right-ascension coordinate is used when calculating the hour angle, it is important to consider the effects of precession on the RA coordinate.

I'm just learning, but the app is providing information asked for by my tracking mounts for current location. It's presented in a night view format, to keep visual distractions to a minimum. And it works on my tracfone android without any problems. I opted for the ad free version, because of data limits for my scenario. Very happy with the app this far.
Does what it needs to do. But I have a few minor issues: I don't like the fact that it's full screen and there is no toggle to disable it. There is a tip button in the about section but all it does is open a share option for the text "Write the email text here". Developer responded about something I misunderstood. Thanks for that. Would still appreciate the app not to be fullscreen.
Polaris is at the correct position when the view through polar scope is not selected but the constellations are not and visaversa when the option is selected. The 2 stars in the dipper that point at polaris don't.
It works but is very hard to use
Useless app. Not useful with polar scopes from Astro-Physics, Losmandy and several others. My review is precise and accurate. The developer is rude, dismissive and confrontational. Not one of the offered polar scope views matches the Astro-Physics RAPAS (Right Angle Polar Alignment Scope.) Not even remotely close. The "New Skywatcher" reticule is closest, but is flipped top to bottom, making it useless. The Bresser reticule is closest to the Losmandy and Astro-Physics PASSIL4 reticules and is useable, but not ideal. The developer needs to improve the app and come up with a new attitude. I'll update my reviews if and when this app, and the developer, have earned it.
