Hello Philippe,
I have an Orion Atlas Pro, EQ/AZ mount. It uses the SYNSCAN controller. My mount is 5 years old, but yours should be same as mine.
I have tried the ASIAIR with my setup but there is a known bug when using the Device.
In my case, I live at location Longitude W75.55 & N39.56 Latitude. When I input these settings or sync with my Apple device, in ASIAIR, for some strange reason it flips the longitude from W to E. Then my mount gets confused.
Several people have posted this same problem on this forum.
ZWO is aware and they are trying to fix the bug.
You can purchase the ASIAIR and see if you have the same issue. Maybe you will be lucky?
I can only advise to email ZWO and ask what they recommend. Or you can wait to see if they will be able to fix.
I hope they do. I like the concept of ASIAIR.
Regards
Dino
