Alternative attachment options for ZWO CAA.

Moontanner

Hi All.
Firstly, many thanks to ZWO for coming up with a reasonably priced way to automate camera rotation with the ASIAir. If I can get it to work on my rig it'll be the cherry on top for this astrophotographer.

I'm in the process of figuring out if I can make the new CAA work on my main scope. I have an Esprit 120 with FF/FR 0.77x (approx. 95mm backspacing needed), Tilt plate, OAG-L, EFW 2"×7, and ASI2600mc/mm Pro fitted, in that order.
It's looking like the CAA might be able to squeeze in slightly in front of the OAG-L?
If anyone has an easy to obtain adapter solution to get this to work, please share. I'll post some shots of all the components so the next person doesn't need to strip theirs down like I did.

ZWO support, do you have the turn radius for the shoulders of the CAA?

Thanks.
Ross.

Here's where I got with my rig and the only spot I could squeeze the ZWO CAA into the existing imaging train on paper:
*Esprit 120 with the 0.77x FF/FR. M78 (m).
*Spacer 13mm M78 (f) to M48 or M54 (m).
*ZWO CAA 16.5mm M48 or M54 (f) to M54 or M48 (m).
*Spacer 10mm M48 or M54 (f) to M48 or M54 (m).
*5mm Thick M48 or M54 Tilt plate adapter screw fixed to OAG-L.
*OAG-L 17.5mm screw fixed to EFW2"x7.
*EFW2"x7 20mm screw fixed to ASI2600mc/mm Pro.

ASI2600mc/mm Pro 12.5mm face to sensor.

13+16.5+10+5+17.5+20+12.5 = 94.5 (perfect for fine tuning the last couple of mm to suit).

I think the above should give me enough clearance between the OAG-L focuser if I replace the focus lock screw and the camera lock screw above it with some inset grub screws. It's not like I ever touch the guide cam once it's in focus with my filters.
The above should give a full 360 rotation without hitting anything, although I suppose 180 degrees is all anyone really needs.

Now all I need is a CAA and some adapters that don't seem to exist. Yippee!
