Not a single problem

I have three of these on various cameras. Not a single problem. You can also reduce required back focus on some QHY cameras if you unscrew the IR cut window threaded into the front of the camera.

OAG head breaks off easily on cable entanglement

The OAG s head is held by 4 small M3 screws and they come off very easily whenever there is a cable pull on the OAG camera wire. In one way it is good and in another way it is bad. The OAG material is aluminium and it is soft metal.
