Hi there,

I have Stellarium and am using it a push-to controller for my telescope using the Nexus II from Astrodevices. On the Stellarium display, it reads what the current azimuth and altitude coordinates are of the telescope, and it also reads the current azimuth and altitude coordinates of a selected object be it Saturn, Mars etc. I am hoping to be able to write a short program for an Arduino that essentially calculates the difference in distance of the target's coordinates and the current coordinates of the telescope, to use with stepper motors down the track but that’s irrelevant. In order to do so, I require two pieces of information, the current coordinates of the target, from which I will subtract the current coordinates of the telescope. I was wondering if there is any possible way I can have Stellarium actually output those coordinates to another program? Or, if there is any program I can write that actually retrieves those coordinates from Stellarium in real-time? Or is there a way I can calculate the distance between the current scope’s position and the object within Stellarium, whilst outputting it in such a way that it can be read by an external program?

I am also keen to hear about any other software that may be able to accomplish this.

I greatly appreciate your time and hope this makes some sense.

Kind Regards, Harry
