Is it possible to add a mount settling time to be used for the "Center" function?

I am trying to use it from the GUI, but mostly it fails, since it re-slews and immediately takes the next exposure, resulting in elongated stars, due to some backlash on my axes, which again makes the platesolve fail.

My mould would be happy with 1-2 seconds setling time, but I would prefer it to be configurable

Hi Rudi, the center script has been working well for me so far. Here is the script I used for years to center. You can adjust the pause to meet your needs.

raOri = Telescope.RA
deOri = Telescope.DEC
Camera.Binning(3)
Camera.Start(5)
Camera.Wait
ra,de = Image.EstimateRADEC
ok = Image.FindCoordinates(ra,de,5)
if not ok then Warning("Solve failed") : end
Telescope.SyncTo(Image.RA, Image.DEC)
pause (4)
Telescope.Goto(raori,deori)
Telescope.Wait
pause (5)
Camera.Start(5)
Camera.Wait
Camera.Binning(1)

Thanks Iver. That will do for me.
I am also asking on behalf of a “senior” friend of mine. Don’t know how comfortable he is with scripts

Hi, the second exposure (option "Verify with extra exposure") is just a visual confirmation for the user, it's not plate-solved anyway. So, trailed stars will be ugly to see, but harmless.
However, if you click "Start" again, that image will be reused for plate-solving, and it will fail as you wrote.

Having said that, it seems that some ASCOM telescopes reports "false" from the ASCOM function "Telescope.Slewing()", even if actually they are still moving a bit, so a possible fix would be a global option for an extra pause everytime the telescope is arrived, not only for the autocenter window. This could be added easily.

That would be a great help
