Hi,
For your 1st warning, do not worry. It is just warning you that you are taking a light field, do not forget remove the cover.
For you 2nd warning, please click the SetupCamera button, in the new dialog, select ASCOM as the Camera Model, then click the Advanced button, You will see the ASCOM Camera Chooser dialog, Select ASI Camera(1) or ASI Camera(2). Then click OK. it should worked.
Thanks
Chad
