Hi @ernst
If I don't mistake Kala is using Swiss ephemeris to for it's calculations.
Swiss ephemeris is a compressed and expanded version of NASA's JPL ephemeris.
So most of Kala calculations is based on the accuracy of JPL's ephemeris created by NASA.
Will it not be wiser to rely on NASA's Calculations about eclipses and Saros cycle found in the following link:
https://eclipse.gsfc.nasa.gov/SEsaros/SEsaroscat.html
Because if they are wrong then the whole basis of our calculations is wrong.....
Dear @ernst
Final conclusion : NASA actually calculates the form and whereabouts of the Moons shadow on Earth for each eclipse. No matter how short it is. (even a few seconds ) just click on any eclipse in the link below to find out how the shadow of moon fell on Earth during the eclipse:
https://eclipse.gsfc.nasa.gov/SEsaros/SEsaros152.html
For example take the July 26th 1805 eclipse:
This means that if NASA has not included an event that astrologically may or may not be an eclipse in it's eclipse list when no shadow was fallen on Earth. So the eclipse was not visible at any point on earth.
If we take Ernst's teaching that astronomy is a great guideline for astrology, then we must not consider an event to be an eclipse when NASA dose not.
Dear @ernst
I absolutely agree with you about NASA calculations. I just mentioned it in this way because some said NASA might have miscalculated the beginning of the Saros cycle.
BTW I used NASA calculations about the place of Moons shadow for the 1805 summer eclipse and was able to set starry night correctly saw the eclipse in starry night.
Thanks a lot
