The bump doesn't affect the AO because it corrects faster than the star shift. TBH guiding with another camera didn't improve anything. Just more USB and power cables to worry about,

That's great Marc - I think I want one too but I don't think I have sufficient back focus on my Newt.

You'll do well with that setup - very impressive.
