ok, I am back and I am having trouble repeating your first step. I have set up simulations for telescope, guide, filter, ccd and astrometry and started Ekos with all things connected. I have the simulators set to represent my current setup with my 9.25SCT at f/10 and my SBIG camera. I have saved those configurations and reload them when I start up. I am able to move the telescope to various targets (m101, m90, m54, etc) and successfully solve using the internal solver (with Source Extractor or not).

After starting Ekos I can see the sensor FOV symbol on the sky chart and it is pointing at the NCP. the angle in the CCD simulator configuration and in the WCS pages both (in the Indi control panel) show '0' and the FOV symbol is pointing at the NCP. I now set the angle in the CCD Simulator configuration page to 25 degrees; save that configuration and exit everything. After starting up again, the angle in the CCD simulator page in the configuration tab at rotation says 25 degrees. But the FOV symbol on the Kstars sky chart is still pointing at the NCP. I cannot seem to get anything to change the angle on the Kstars chart.
If I do a solve and it comes up with a different angle, (usually 90 or -180 or close to those) then the solved field image on the skychart is in that orientation and the FOV Symbol is also. But it does not change by my making any other changes to the configuration setting of the CCD simulator.

There seems to be to be a total disconnect there. I will re-read this thread a third time to see if I am still misinterpreting what that rotation angle (in the Indi control panel configuration pages) means, but what ever it is it does not seem to be reflected in the skychart.

That symbol is generated by the plate solver, so naturally it will not update until after plate solving again.

ok, that may be. All I know is that there are a couple of symbols. One is the image of the plate solve, the other is supposed to be the FOV of the CCD. Obviously, the first one matches the plate solve, but the second (the one you can click on and off) should (by my thinking) follow what you set for the CCD. Otherwise, what is the reason for being able to set the rotation angle in the WCS setting of the CCD?

It is fine, I can work with what we have. I understand a lot more now, that is all that matters to me. The Kstars skychart does not really provide much information for 'composing' an image based on CCD rotation anyway. And for finding a guide star I have to rotate and look for one.

It is all good, I just needed to know how things were working.

thanks

The WCS field in the driver is populated by the solver, it is not something you have to set.
As for updating the custom FOV, that may be desirable in terms of the rotation. But otherwise they are not auto-generated. Nor would that be desirable. As it is,I mainly use them to compare the framing between different configurations of my equipment.
And you can get more information on the sky chart for composing by turning on DSS under HiPS All Sky Overlay.
