Thanks Dave - good ideas. I've already got the Losmandy D plate on order for the top.<br />
<br />
Good idea about the felt/glue/styrene. It seems pretty rigid right now, but my next logical step would be getting rid of the 3-points indeed.<br />

Jeff, I think you should get another Losmandy D top plate and then a ring set for the 72. Then remove the felt, clean off the adhesive residue, cut strips from 0.030" (0.762mm)-thick sheet styrene (available at hobby shops), and affix them to the inside of the rings with super glue.<br />
<br />
I did this and my differential flexure dropped to almost nothing.

UPDATE! Bought an Astro-Tech AT72ED scope to replace the Orion ST80 shorttube. Came today in the mail, mounted it atop the triplet, and looks good. Here's some pictures:<br />

So I sold the SSAG and got a Starlight Xpress Lodestar for guiding with the ST80. I will probably sell the ST80 in favor of an Astro-Tech ED72. Here's the start of the review of the Lodestar:<br />

Yes, the ATFF should be 57mm from the image-plane/CCD chip. In this config I have it at 53.7mm, which is close enough.<br />
<br />
If you look very closely I have the little spacer on the front (side with the printing) of the wheel. This spacer comes with the wheel. This is the only way the ATFF will attach/screw-in as otherwise it hits the filters, when they rotate. And, it pushes the ATFF 2 or 3mm further from the chip, which is good in my case.
