Flats issue after image session

ing the following error when trying to create flats following image session.
“Action Aborted for Error : Object reference not set to an instance of an object.”

Hello George,

i used the description of problem i received by email this night for better understand your asking.

For taking flat the mount is required like configured control.
If you dont want to user your normal profile please add a simulator mount (ASCOM) in the profile created for flat.

I’ll add a better error string on this.

All the best
