My Edge 8 looked the same except I'm a visual guy so I just used the 1.25" visual back that holds a 1.25" diagonal that threads on the threads shown in your photo. Any other accessories would simply thread on those same threads.

I see one mirror lock and I guess a focusing motor attached to where the focus knob would be. Th second mirror lock is probably just hidden by the visual back.

you need to start with the edge hd t-adapter 78.3 mm it screws apart if u use with the reducer to make it shorter

21 mm spacer

16.5 mm spacer can be replaced with zwo oag

11mm spacer usually already attached to the zwo camera

6.5mm to zwo camera sensor red painted edge to the camera sensor

 

u may need an adapter to change thread from m48 to m42 between the edge t-adapter to the zwo 16.5mm spacer

and that is the standard hex nut on the back of your edge. it looks just like mine.

 

all this will equal 133.3 mm u can private me if u need more pics
