Hello, an updated ASCOM plugin (version 2.20) is now available at the Astroart web site:
http://www.msb-astroart.com/
It's a minor upgrade, it's now possible to connect to the camera without using the ASCOM Chooser (to save time, and to avoid problems with some recent ASCOM drivers).
By the way, it's already possible to avoid the ASCOM Chooser and to connect all devices at once (telescope, focuser, etc.) also with CTRL+Click on the Setup button.
