This isn't obvious to me from the documentation, but is a separate guide camera required when running EKOS?
It'd be nice to know what the minimum hardware requirements are but I can't tell from the documentation.
I realize explaining this is complicated by fact that one can simulate all of them for training purposes.

I can start the server and capture images with just  a mount and CCD, but I haven't successfully run the alignment tool.
 

No guiding is optional and is used for long-exposure astrophotography.
