Many thanks to you and Bald Eagle, I was not aware of it because I 
didn't look into all POV newsgroups regularly. I just downloaded the 
files from github and will take a close look within the next days.

If someone is interested: The hipparcos data can be found at

https://cdsarc.cds.unistra.fr/viz-bin/cat/I/311#/browse

FTP-Tab, hip2.dat.gz

For my image I need declination, right ascension and magnitude. But I 
wonder about the colour index and if this can be of use.

Best regards
Michael
