Thanks for the responses Ivan and Bogdan. I should have clarified that I do have most things working. My questions were just trying to confirm that I used the most efficient approach. I did read the documentation, wiki, and studied the API and other plugins to get a handle on things. They were all

Hi Gour, Yes, I did read the information you have quoted. I agree that the Swiss Ephemeris looks useful to Stellarium and has a compatible (GPL) license. However, as a trained research scientist I am very fussy about sources and accuracy and I would like to see at minimum a peer-reviewed paper di

Hi! As far as I know, also the VSOP87 has a temporal limitation and was derived to provide good results for about the years -4000...+8000. But I don't know the exact behaviour, i.e. how fast it diverges from nature beyond that range. Or can you please define "almost no limit"? An improved VSOP so
