@Jari Kirma, very interesting post!
If you're looking for even more Wolfram Language eclipse computation, check out Stephen Wolfram's new book "Predicting the Eclipse: A Multimillennium Tale of Computation". You can grab a copy on Amazon: https://www.amazon.com/Predicting-Eclipse-Multimillennium-Tale-Computation/dp/1579550878
Very interesting map! It's a great idea to connect the maximum eclipse locations as you did with the dashed lines.
