Hi Gary,
This may be the easy way to get the pointing information:
https://ssd.jpl.nasa.gov/horizons/app.html#/
And while they do not have a nominal Artemis ephemeris at present they do provide a notice that Artemis data will not be available before a time around TLI. (14 Nov 07:19 Z)
The site also can be used for the Webb telescope ,and the output can be customized to include apparent RA,DEC and Alt Az on a customizable time basis.
There is an input for the observer location, and I think the parallax is consistent with the RA,DEC. difference between regular and apparent for their Webb data.
It looks like a very workable format.
I played around with a couple of python libraries: skyfield and astropy. While interesting there is learning curve that's out of scope for next week.
Thanks for the helpful forum discussion. I'll post a follow-up on what happens one way or the other.
Dave
