Stellarium Long-Time High Accuracy Installation

Stellarium is a powerful tool, but you have to know its limits and how far back it can display accurate data based on ephemeris calculations. Have you ever seen the sun displayed off the ecliptic line when looking at the distant past in Stellarium? This video will show you how to install more accurate ephemeris data for more extended time periods using NASA's JPL DE430, DE431, DE440, DE441 data.

Here is the link to the JPL download directory to get the files:
