Alan:

I feel fairly certain that you are wrong about the inverting being due to the telescope optics.

The reason I can say this is that, with nothing changed about the scope, its focus and what it is pointing at, with the camera in and connected to my Rasberry Pi, I can take a preview with the program CCDCiel and the mountain is shown right-side up. Then, I exit CCDCiel and start EKos and do a preview. The mountain is shown upside-down. This tells me that there is either a bug in EKos, or, much more likely, a setting in EKos that I don't know about which is inverting the image. I would like to know what that setting might be. Or possibly, CCDCiel is automatically inverting the image to make it right-side up, and EKos is not.
