I would like to use an EF lens with the 2600mc duo. I have seen this adapter
https://www.zwoastro.com/product/zwo-new-eos-t2-adapter-suitable-for-all-asi-cameras
2 questions that come to my mind:
1) would it screw with th M54 female tilt adapter of the DUO?
2) can I screw a 2" filter inside the adapter?
