Has anyone had good luck (and details) about setting up Wanderer ETA in the context of a Pegasus Astro optical train (rotator, oag, filter wheel) + ZWO ASI camera?

I do have some backfocus space, but I remember reading there were some problems with that kind of setup.

I think you'll need spacers between the ETA and Rotator to allow the motor "bumps" on the ETA to clear the back of the rotator and actually allow rotation.

For me it takes (left to right): 4mm + 9mm + 1.4mm = 14.4mm

You'd need to have that much spare back focus in addition to the 55mm OAG/FW/Cam + 10mm rotator, or about 79.4mm total.

Not sure things would fit for me attaching the ETA to the rotator; I was thinking more along the lines of camera→eta→efw→…
But I’ll take a closer look; thakns!
