Camera FOV and rotation synchronization via NINA platesolving

[Quark-Coder]

Using NINA and telescope simulator, i can transfer information about the position of the telescope using platesolving to the Stellarium. In the stellarium itself, the position of the telescope is shown as a crosshair, which is located in the center of the platesolved image. Is there any way to show not just the position of the center of the image, but also the camera's FOV, as well as its rotation?

You can probably do something using the Oculars plugin properties and RemoteControl API. Try interctive scripting first, using http://stellarium.org/doc/24.0/group__oculars.html#a351c58375eb65df7cb39f736f37e4941

I see commands like Oculars.selectTelescopeAtIndex(n), Oculars.selectCCDAtIndex(n), Oculars.setSelectedCCDRotationAngle(angle), etc which should all be scriptable.

I just thought that Stellarium already has this functionality and I just don’t know how to implement it. I've never written scripts for Stellarium before =)

I came to this solution: using the curl --silent --request GET http://localhost:1888/v2/api/equipment/rotator/info | jq -r ".Response.Position" I get the angle of rotation of the image after NINA platesolve. After that, I need to substitute this angle in the Stellarium script:

TelescopeControl.centeringScreenByTelescope(1);
Oculars.selectCCDAtIndex(1);
Oculars.selectTelescopeAtIndex(22);
Oculars.toggleCCD();

var angle = 10;
Oculars.setSelectedCCDRotationAngle(angle);

How to do it? I just don't understand what specific programming language Stellarium scripts uses, and I don't understand how to implement a curl query in script.
Another question is how to determine the moment when the Sync command is sent to the Telescope Control plugin? So that after the telescope crosshair moves, the CCD angle is also updated.

I took a different route. Instead of creating a stellarium script, I made a python script that directly controls stellarium via POST requests.
