OAG-L to Crayford ?? or OAG-L to SC14" using celestron reducer f/6.3

Hello

My camera is ASI2600mc and 174mini for guide and my telescope is SC14"
I have celestron reducer f/6.3

So, how can I conect my OAG-L to my telescope?
I would prefer to conect to my 2" crayford

I don´t know the piece I need

**ASI2600mc is conected to OAG-L with M54 adapter

Thanks

Thanks a lot
I have seen this link many times
Many times….

But I have no idea, I am not sure what I need to conect OAG-L to my crayford (on that link it down’s appear)

Or yo my focal reducer celestron f/6,3

I would be grateful if someone let me know what is the piece I need

Thanks

On that link there is no piece to conect to my crayford or focal reducer
