Hello, an updated plugin for ASCOM cameras is available at:
https://www.msb-astroart.com/down_en.htm#cameracontrol
which fixes two possible problems:
1) Setting an invalid temperature could block the plugin.
2) The ASCOM Chooser may not show up.
If these two errors do not affect your camera, there's no need to upgrade now.
Clear skies, Fabio.
