Circular Star Tracks

[PLANETARAS]

Hello everyone. I'm trying to make a script to visualize the circular tracks of the stars during the 24 hours. Through the marker and editing the Analemma script, I was able to visualize the Arcturus track. Would it be possible to select multiple stars at once to view tracks together? Does anyone know how to select the seven stars of the Big Dipper

Same way, just use a few markers ;)

Thank you, great success, I will create a beautiful script with your advice

Interesting. You can probably remove stuff around labelWeek.
We (@10110111 , @alex-w) should maybe come to a solution on #1888...

I work by trial and error and it's very interesting. Yes, in fact, already done. Here's the script :

core.selectObjectByName("Dubhe", false);
StelMovementMgr.setFlagTracking(false);
core.selectObjectByName("Merak", false);
StelMovementMgr.setFlagTracking(false);
core.selectObjectByName("Megrez", false);
StelMovementMgr.setFlagTracking(false);
core.selectObjectByName("Phecda", false);
StelMovementMgr.setFlagTracking(false);
core.selectObjectByName("Alioth", false);
StelMovementMgr.setFlagTracking(false);
core.selectObjectByName("Mizar", false);
StelMovementMgr.setFlagTracking(false);
core.selectObjectByName("Alkaid", false);
StelMovementMgr.setFlagTracking(false);
core.wait(2);

for (i=0; i<1440; i++)
{
var minute = i + 1;
core.setDate("+1 minute");
var info = core.getObjectInfo("Dubhe");
var az = info.azimuth;
var alt = info.altitude;
MarkerMgr.markerHorizon(az, alt, true, "gear", "#ffffff", 1);

core.wait(.01);    

var info = core.getObjectInfo("Merak");
var az = info.azimuth;
var alt = info.altitude;
MarkerMgr.markerHorizon(az, alt, true, "gear", "#ffffff", 1);

core.wait(.01);    

var info = core.getObjectInfo("Phecda");
var az = info.azimuth;
var alt = info.altitude;
MarkerMgr.markerHorizon(az, alt, true, "gear", "#ffffff", 1);

core.wait(.01);    

var info = core.getObjectInfo("Megrez");
var az = info.azimuth;
var alt = info.altitude;
MarkerMgr.markerHorizon(az, alt, true, "gear", "#ffffff", 1);

core.wait(.01);    

var info = core.getObjectInfo("Alioth");
var az = info.azimuth;
var alt = info.altitude;
MarkerMgr.markerHorizon(az, alt, true, "gear", "#ffffff", 1);

core.wait(.01);    

var info = core.getObjectInfo("Mizar");
var az = info.azimuth;
var alt = info.altitude;
MarkerMgr.markerHorizon(az, alt, true, "gear", "#ffffff", 1);

core.wait(.01);    

var info = core.getObjectInfo("Alkaid");
var az = info.azimuth;
var alt = info.altitude;
MarkerMgr.markerHorizon(az, alt, true, "gear", "#ffffff", 1);

core.wait(.01);    

}

Just try it:

var stars = new Array("Dubhe", "Merak", "Megrez", "Phecda", "Alioth", "Mizar", "Alkaid");
StelMovementMgr.setFlagTracking(false);
core.wait(0.1);
for (i=0; i<240; i++)
{
	core.setDate("+1 minute");
	core.wait(.01); 
	for (j=0; j<stars.length; j++) 
	{
		var info = core.getObjectInfo(stars[j]);
		MarkerMgr.markerHorizon(info.azimuth, info.altitude, true, "disk", "#ffffff", 1);
	}
}
