The Aisair will only work with the EAF. You can use the EAF if you purchased one of their SCT adapter brackets. But honestly, I had an E EdgeHD 9.25, you won't be happy with it if you want to install it for autofocus and astrophotography purposes. Some people report having success with it but most, like me, had problems. The issues is that SCTs have mirror shift when adjusting focus and the Asiair does not take that into account, it makes the adjustment and then immediately takes the measurement while the mirror is still moving making the measurement inaccurate. There are better options.
If you intend to focus manually then it should be more than adequate.
