The Photographer's Ephemeris

I'm not sure  if this has been discussed before.  There is a free (desk top) app called the Photographer's Ephemeris.  it shows the angle of the sun and moon at any moment on any day anywhere in the world.  If you need to know on what day will  the sun rise directly over something , you can know without trial and error,  I find it essential for autonomous drone flight programming and sunrise photos and videos.

There is also an IOS app but that is not free.

  • Another option is SunSurveyor... it's similar to the others. :)

     

  • The main reason I like  Photographer's Ephemeris is that it has a free desk top version.   When I program drone missions with the Litchi mission hub.  I put Mission hub on one monitor and the Ephrmrtis on the other.
