I'm probably doing some dumb here, but I can't work it out.

My setup:

• Focuser is attached to a Pegasus Ultimate Power Box V2.
• I'm using Ekos/INDI.
• I've setup the Pegasus as an AUX1 connection in the Control Panel.
• The Pegasus connects fine and I've got a Focuser tab where I can manually control the focuser.

However when I go into the Focusing tab in Ekos, I have no focuser available.

I have not got a Focuser setup in the Control Panel which is why I assume Ekos is showing nothing. If I try to select any of the Pegasus options in the Focuser list, they do not connect.

Any pointers for what I am doing wrong? I am assuming that this is actually possible to do, of course.

Make sure the focuser is selected in Optical trains.

Go to your camera and click the edit button (next to your first optical train - Usually Primary).

Then select the UPB under focuser.

Yes, right on the money, thanks. Knew it was something dumb I was missing. Forgot about that!

Not something Dumb. Optical trains are still fairly new. Sometimes I even forget!
