As said originally, EKOS is not previewing from my guide camera tho other applications can find the camera on the USB3. In the following screenshot one see my profile for the ZWOASI178mc -iOptron (on Orion Guide Scope) and the iOptron cem25 mount:
Starting that profile I get the next window (Main Control for iOptron, etc) Here note the error messages. EKOS is looking at various ports. There is no wifi, nor bluetooth connection. There is only the serial connection to the ZWO and implicit ST-4 connection to the iOptron. See the Serial connection mode and ports are live. The ZWO camera is also live per the ZWO Main Control Tab
In the 3rd window shot below see Scope Properties and Scope name is populated and green for go.
Now below see the Guider Screen. Note the ZWO is selected but as for Via, then what? I want EKOS to talk to the mount thru to the ST-4. SO that's talking back to the camera isn't it? In any event there is no other choice in the pull down option . I also have provide guide scope specifications in another window lurking about somewhere if I can find that.
In the shot below see the iOptron is not connected and the message. ERROR] Failed to connect to port (/dev/cu.usbserial). Error: Port failure Error: No such file or directory. Check if device is connected to this port.
But again note my other applications on this Mac are able to communicate with the ZWO. They are off now and there was a reboot to clear connections, but if I go to the other apps they do find the camera working - imaging.
Finally coming full circle back to the Guiding Windows. The mount is disconnected.
So:
1) Why is there no image at all from the ZWO camera and
2) Why is the mount not connected (via the St-4 connection).
