Connecting ZWO OAG to Celestron C8 or any SCT

cward83

I have a ZWO OAG, but I cannot connect it to an SCT. There isn't enough clearance at the back of the OTA in order to screw it in. The threading doesn't seem to be right either, and it cannot connect to either of the two Focal Reducers I tried.

Back of OTA -> ?? -> OAG

Can someone help me out on this? I got this OAG second hand and it seems to have come with all the accessories however there doesn't seem to be a way to connect it to an SCT, as the top guide camera opening butts up against the back of the OTA.

Any help much appreciated.

The accessories come with ZWO OAG can connect the telescope which has M42 or M48 thread. Be sure your telescope has the same theard.

But wait... what is the threads on the actual OAG? T2 threads?

The thread on the actual OAG is M42, you could see the details on the attachemt which I send to you.
