By default, Skychart install only a small JPL DE430 file valid between 2000 and 2050 to not make the installer too big to download. Then out of this period it use a compact library based on DE404 that can compute the planet position between -3000 and +3000. To extend this computation you need to install another JPL ephemeris file. For your case you must install DE431 (beware this is a 2.5GB download) that can be used to -13000. See this page for information how to install the file: https://www.ap-i.net/skychart/en/documentation/solar_system#ephemeris Do this solve the issue? |
