in your case, on the telescope side, it'll connect with an M48 to the flattener, and then the flattener would use the M48toM68 adaptor and screw into the moonlite drawtube?

flattener will then go into the standard skywatcher focuser on the ED80. The Moonlight will be on my RC8, and Moonlight sell a M68 to M48 adapter, no flattener for the RC8)

on the camera side, you might want to get the EOS adaptor for the TS9OAG.
what this does is keeps the distance from the CCD to the OAG plane at 55mm which works for most flatteners and coma correctors.
without this, you'll be adding 10mm for a conventional T2 to EOS adaptor which'll make the distance 65mm.

Yep

so you'll need to get the EOS and M48 version of the TS-OAG.
yep, it is not rock solid, but for a 9mm profile, it absolutely works once you get everything tight.
with my 1000D, I kept the guide port at the bottom of the camera so it doesn't interfere.

So do you think any guide cam should be ok, as it appears the stalk clears the bottom of the DSLR, so guide cam width (like the ASI120MM) shoudn't be a problem?

and for handling weight, I was skeptical on whether it would support my SBIG and 7 position filter wheel, but it does. so no issues there.
you can also get the T2 to C-mount adaptor/extension for the guide camera to fix your guide cam. I'd suggest using a threaded adaptor for the guidecam than the standard one. that way, once focused, you don't have to refocus the guidecam even if it is removed as you just screw it back on without moving the stalk or holder.

The ASI120MM has the T2 thread so would go straight on the stalk, as long as it doesn't hit the DSLR
Thanks.
