I think there is a confusion about how this command work, maybe the documentation need to be improved.

MOVESCOPEH do not move the telescope cursor to RA position but to hour angle, declination.
By definition the hour angle is in range -12 to +12 so 15 is out of range.
Also the parameter for this command is RA and DEC in decimal form, without any other text.

For example "MOVESCOPEH -1.0 0.0" show the cursor on the equator, one hour before the meridian.

Use "MOVESCOPE 15.99 +21.47" to show the cursor at a specific RA,DEC.

Do this work for you?

Thankyou for helping me understand.
I tried MOVESCOPE no errors reported, it places a camera and field of view position for the telescope on the Sky chart stellar plot but does not move the telescope.
I tried SLEW which did move the telescope.
I am open to other suggestions, my goal is to move the telescope so to make a mosaic following the mosaic file made by Sky Chart.
Thanks

Yes MOVESCOPE name is misleading, it only show a mark on the chart.
This is because this command was added to support telescope mount that not have a standard interface but only a script that can be used to display the telescope position.

SLEW is the right command to move the telescope.
Be careful the coordinates need to be for the equinox of the chart, the precession for the specific telescope driver setting is made by the program.
If you read the coordinates from the mosaic file this is the right one and no conversion is need.
In doubt you can use the command GETCHARTEQSYS that return the chart current setting.

I see in your script comment a link to the command description translated in Spanish and Dutch, be careful this translations are not current and it is better you refer to the English page:
