Summary0002949: Cannot Connect to Telescope
DescriptionI have an EQ6R-Pro, which I run remotely via PC through ASCOM and EQMOD (also installed). Unable to add EQMOD.Telescope to the telescope connection window in Cartes du Ciel. It always defaults to POTH.Telescope under the Telescope connect window. Even if I try to change the telescope, the drop down in the ASCOM telescope chooser window shows nothing. It is literally blank.

I can control the telescope successfully with NINA and Stellarium, and both are working flawlessly with ASCOM and EQMOD. But I want to stop using Stellarium due to its slower-than-molasses performance and permanently switch to Cartes du Ciel. However, I am unable to do so. I am attaching a couple of images to show what is happening. Not sure how to fix it.

This look like a serious issue with the Ascom platform installation.

The empty list is in the Ascom Chooser tool, not something that CdC can control.

I think you can get help directly from the Ascom developer.
You can reach them here: https://ascomtalk.groups.io/g/Help

Be sure to send them the screenshot that show the "string to boolean " error.

Requesting closure of the issue. I resolved it by completely removing ASCOM and then doing a fresh reinstall. Cartes du Ciel now is connecting to the mount via ASCOM. Problem solved. Thank you all.
