Thanks, Reiner. Excellent work-around for me. I can use 1 minute increments
in the JPL Horizon's generator-- I never noticed the RA and DEC coordinates
changing as I rolled the mouse pointer around in Astrometrica. If anything
"develops", I will post an image, even if really stretched.

Thank you.

Hi: I performed a plate solution for one of my images and was able to use over 800 stars in the solution with good residuals. Is there a way to allow...

Astrometrica loads the MPCORB.dat file with the heliocentric orbits of minor planets, it also handles COMET.dat with the cometary orbits, as far as I know...

... Yup. And even if Astrometrica would import some elements file for artificial sats, there is no chance they would get plotted anywhere near the true...
