Rick1952 i use the following connections:
- guide camera and filter wheel go into the main camera
- main camera goes into USB3 port of the ASIAir
- focuser goes into the USB2 port of the ASIAir
So, there should be enough ports available on the ASIAir to connect your mount.
Edit: i use a ZWO astro camera as my main camera. Not sure if this fits your scenario.
Good luck,
Olli
