Astro Locator makes it simple for astronomers to get their OTA "polar aligned" quickly and easily.

It is of particular benefit to new astronomers who set up and break down each session, so is of great use to those without the luxury of an observatory.

Astro Locator’s primary purpose is to help find Polaris or Sigma Octantis quickly and easily, so ensuring that the astronomer can get polar aligned quickly and easily.

Displaying the current direction, elevation, latitude and longitude, altitude, moon phase, sunrise and sunset times as well as astro twilight times.

All data required to quickly and effectively locate Polaris or Sigma Octantis displayed clearly on one screen.

Astro Locator shows correct elevation.

Accurate time shown in both UTC and local time zones for accurate setup and Iridium flares.

View sunrise and sunset times, as well as astro twilight start and end times to know when viewing and imaging is possible.

See the current moon phase.

Today Extension: Whilst the sunrise & sunset, and astro twilight times are of course available within the app, they are also available for quick access as a Today Widget. Just a quick swipe down to view the days information.

Great to hear that all is now working ok. If you see issues with directions like this, it is usually either iOS / the device or interference. A force restart of the device, or moving it around in a figure of 8 type way usually helps. Any issues, drop me a message via the app. Thanks. Neil.
