There is no elegant option. You would need to create your line using an image and the image command (use equatorial coordinates).

other option is to invent a "constellation" only with the big dipper and the line to polar star and then read "this new constellation".

It'll depend of your image of arrow you'll create and need.

We can't create the code for you.

It'll be of this shape:

image action load name fleche1 filename coordinates/fleche.png coordinate_system equatorial alpha 1 scale 45 altitude 80 azimuth 0 rotation 90
script action pause

But you'll have to find the good parameters for it to fit the good position.

An other option would be to create it as a nebula if you want to keep it even when the script is ended.
But it's far more complicated.

I already made this kind of object but as a sky_culture. Far better but even more complicated to use.

Best regards,

Hi Raul (astrodidactico),

Your idea is good but I suggest that you create an arrow as a constellation art figure to separate the asterism and the indication. That's what I did.
