Am primit raspuns si de la Celestron:

Thank you for contacting Celestron Technical Support Services.

The ideal back focus for the F/6.3 reducer-corrector 105mm, however, it is not that critical you can be off by a couple mm. You may need to get a custom adapter made to attach the SCT threads to the m48 threads.

hope this helps. If you have any other questions please let me know.
