When I’m using the Astro Physics APPM program for making a pointing model - and have the model start near the Zenith as its first point - the dome does not move until the mount finishes moving to the Zenith. This causes an issue where the camera starts taking a picture before the dome has a chance to finish getting into position. I’ve spoken with Ray over at Astro Physics and the RA/Dec coordinates for the mount are sent as soon as I hit “Run” on the APPM program. Why isn’t SGP immediately moving the dome once the mount starts to move?
I’m guessing that SGP is using J2000 coordinates (which I imagine AP is using as well). Being as how this is math - and computers tend to be pretty good at math - the time to calculate that Azimuth position the dome needs to go to happens in a nanosecond? So why does the dome just sit there and not move almost immediately once it receives the RA/Dec info from APPM?
Is it the Nexdome driver that should be moving the dome physically and SGP just provides the Azimuth?
