The current setup in the observatory.  The Canon EF 70-200mm f/2.8 L IS USM II is piggybacking on the TS-115, taking wide field images at 135mm f/4.  Yes, that's right! I'm using a telesphoto lens as a wide-field imaging scope. Who knew?

If you're going to do this don't forget to turn off image stabilization.  It matters, a lot.

The mount is a Celestron CGEM-DX with the ADM upgrades that I got in 2012. I hypertuned the mount in July '22 and the improvement in performance was worth the effort and expense.  As long as the motors hold up, I'll keep using it.  Now that I know how to service the mount I'll be more inclined to perform the service on a routine basis.

I have the AVX with the ADM saddle, huge improvement! No more destroyed dovetail bars.

I pretty much did the same to the CGEM-DX by replacing the stock saddle with the ADM dual saddle.  Nice to have the ability to change between mounting plates if the need arises.  I mostly use the D-style plates anyway, but there have been a few times when it's been very handy to have around.
