Hi

It is solved by setting the "bad pointing sample criterion choice" to 5.
Default value for "bad pointing sample criterion choice"=0.5 degrees

Now I have realized why this error message appeared.

My setup includes:
- Skywatcher HEQ5 mount
- Vixen ED81s
- SBIG ST2000xm camera

I performed a draft polar alignment with the mount polar scope. After connecting the mount via ASCOM, I slew to Vega.
I noticed the telescope was pointing some degrees away. Since Vega was not in the camera field of view, I moved the mouse in RA/DEC with the gamepad controller in order to bring Vega in the camera field of view. I captured a image of Vega with the skyx camera addon. In the fits header of the file I sent to you you can see

OBJCTRA='18 22 25.562'
OBJCTDEC='+34 15 58.26'


After finding the astrometric solution of the image with skyx you can see

Center RA: 18h 35m 58.41s
Center Dec: +38° 46' 57.3"

The angular separation between these two positions is more than 0.5 degrees.
This is why Image Link is failing.

So I guess I need to have a good polar alignment next time. Perform a synchronization of the mount in the first time.
After that proceed with the image link.

Thank you
