In summary, the conversation suggests creating a catalogue of stars along the ecliptic using RA/Dec coordinates, which may seem daunting. Suggestions include downloading a catalog and using a computer program to compile new data files, or using the UCAC 2 catalog and a program to extract stars manually. Another option is to use the VizieR Service, which offers a .txt format for extraction. The possibility of using Ecliptic-coordinate databases for deep space probes is also mentioned, but no mention of such databases in online star catalogues is found.
Download a catalog and then write a computer program to compile new data files.
If you have little programming experience, the following will work as well. Download the UCAC 2 catalog (http://www.hnsky.org/ucac2.htm [Broken]) and a program that let's you extract stars from the catalog using input parameters (http://www.projectpluto.com/ucac2.htm). If you use this program, you will have to manually determine the appropriate window size and RA and Dec points along the ecliptic for each extraction.
EDIT: You could accomplish the same (but for any catalog) by using the VizieR Service (http://vizier.u-strasbg.fr/viz-bin/VizieR). The standard output is in .html format and I do not recall if .txt format is an option--I just checked, yes it is.
Thank you for your prompt reply. I will investigate the VizieR Service.
In the meantime, I read that NASA uses Ecliptic-coordinate databases for deep space probes, but I find no mention of such in lists of online star catalogues. It would be ideal if I could download such a database and make a simple extraction from it.
