OK, I've arrived at what I believe is my final configuration:
I'm using a Celestron CG-4 mount/tripod with dual axis drives for tracking. I've also attached an Apertura 'D' style bar to the scope and an ADM dual mount saddle to the mount.
Here are some things that have worked and not worked for me:
The mount - I started with a used Explore Scientific Twilight 1 alt/az mount. As the scope comes out of the box, the TW1 is a pretty good mount, I didn't notice any vibration as I was focusing the scope. However, because I want to be able to move my scopes between mounts I wanted a 'D' type plate on the scope and a 'D' or dual 'D' and 'V' saddle on the mount. Once I added the weight of the plate and saddle, along with the 2" prism diagonal and Daystar Quark, vibration became a problem. Additionally, I was finding clearance problems between the focuser knobs and controls on the mount. There really wasn't enough room to fit my fingers between the two. Additionally, trying to track the sun which filled or nearly filled the view while trying to perform cell phone photography was an exercise in frustration. I felt I really needed tracking, though not full on GoTo. I believe the CG-4 is an economical solution.
ADM does not make a saddle that replaces the CG-4 saddle, unfortunately, but Anthony does make a saddle that has a 'V' style bar on the bottom. I've installed it and regard it as permanent, though it really isn't. It works very well.
Baader Click-Lock eyepiece/diagonal clamp - I have one that fits on this focuser and works tremendously well. However, I noticed that with the stock configuration many of my 2" eyepieces only left about 3mm of in travel available. To avoid potential issues I removed the Click-Lock and returned to the stock pressure clamp, which works just fine.
As configured I estimate this rig weighs in the neighborhood of 35 pounds. I can easily pick it up and carry it around but I would hesitate to classify it as "grab-n-go", primarily because of the bulk of the set up. I can't imagine carrying it through doorways without having to loosen the spreader and fold the legs in, and with the counter weight bar protruding on one side and the focuser on the other, collisions with door frames seems highly likely. Fortunately for me, I'm not a grab-n-go kind of guy but a planner so this will work well for day and night viewing for me.
