Barlow to DSLR connection advice?

[glend]

I have a GSO 2" ED 2X barlow that I would like to add to my imaging setup and attach to my Canon 450D. Anyone have any experience with doing this? I'd like to retain the Baader MPCC coma corrector in the stack as well. Can I just unscrew the bottom element of the barlow and attach it to the coma corrector using a thread adaptor of the correct thickness?

yes, most likely youll get less magnification doing this -with d-slr & barlow only it works easy -im not sure how the MPCC will impact -youll have to test it

I would probably just remove the MPCC but its worth a go, it might vignette?
