Using 2600MC Duo with Omegon Pro RC 8 and TS-Optics 2" CCD 0.67x for RC reducer

Hello there,

I want to use 2600MC Duo with Omegon Pro RC 8 tube and TS-Optics 2" CCD 0.67x for RC - focal reducer.

Focal reducer have M48 x 0.75 thread for the camera side and 2" to the scope side.

Do I need other / some adapters? It will show a clear image in guiding sensor, with no vigneting?

Thanks a lot
