Hi Ken,
This is a major ask, but could SGP be modified to provide accurate pointing to a moving solar system object?
Asteroids can move rapidly and may not even be in the FOV if the sequence target time is not current. Calculating the RA and DEC at the start of a slew to an asteroid or comet would position the beginning of such an event to be at the right spot at the right time. Although fine for astro-imaging, this capability would enhance SGP usage for science as well.
Regards,
Kent
