As expensive as they are, 10 micron mounts may be worth looking into. They are very popular in spite of their high cost. I've never seen a review of one that said they were anything less than excellent. The other, lower tech option that's more similar to your Ioptron mount is the Mesu 200. It's driven by a high precision steel roller bearing and has very low PE.

Oh, and I'd also mount the scopes side-by-side. That should lessen the amount of leverage applied by the second scope, and let you use less counterweighting.

I really like your Pleiades shot. There's some nasty rainbows around the edge that may disappear with flats though I'm no expert on the RASA. Also your star images look a little misshapen. This may be due to the cable on your camera (I presume there is one!) or it could be that it needs collimating. Those super-fast optic systems can be tricky to keep accurately aligned.

I'm excited for your plans. Best of luck with everything!
