plumbing the rear cell on a C11 ?

Question; if I attach a 6.3focal reducer/cor. to the 2" threaded rear cell of my C11 will I be able to thread the 2" opening of a WO fine focuser then attach my 2" dia? will that be too much out focus. The other way would be to first attach the reducer then a 2" visual back, and then a Diagonal... excluding the focuser... thanks, John M

John,

I think this order should work: (I verified I could do it with my C11 using a JMI focuser)

1) WO Focuser,
2) 6.3 focal reducer (requires 2" male to SCT thread adapter),
3) 2" visual back,
4) diagonal.

You will have limited view to the zenith with this arrangement if you are still fork mounted.

Note: My JMI Focuser includes a large SCT thread adapter and thus is attached directly to the C11 rear cell.

Regards,
