Can I couple a focal reducer with an off-axis guider (C9.25" SCT)?

Hi all,

I'd post some of my own pics if I wasn't so intimidated by the mind-bogglingly incredible photos that pass for "beginner" around here, so I'll bide my time.

I'm at a point where I'd like to start auto guiding, and have decided that an off-axis guider would be ideal. No flexure or extra mounting to worry about, keeps my rig portable and simple. I have access to dark skies and realise it may be more fiddly to find guide stars.

This means I will have two focus points, the OAG CCD and the DSLR that will hang off the end. Can I still add the focal reducer as below? Any caveats?

OTA -> OAG -----> FR ----> DSLR

| -----> CCD (Nexguide ideally)

Any advice appreciated.

Thanks in advance!

Dylan.
