Thanks Guys!

Would that work?

Cheers,

Sounds familiar Peter and an interesting idea.

I have my reservations about making the threads non-concentric with each other. This would be quite costly. Also, yes, you could lock it down at the desired location, but this will alter your backfocus. This would most likely need another adapter to then get your backfocus right. I think probably the cheapest and simplest way would be to use a dovetail that has a couple of millimeters of lateral movement, by which the camera can be moved left, right, up and down.

I could see a need for that Paul. Something like a "tube ring" to go around an adapter which then has a CW bar threaded into it.

Greg.

That's a great idea Greg, something that could be built.
Is there a big need to be able to rotate the OAG/guide cam separate to the imaging camera, especially with square chips, as opposed to rotating the guide cam and imaging camera together?
