Wow. That mount looks suspiciously like my old CG4, and the biggest thing I put on that is my 80mm f/15. Even that has a teeny bit of shake before it settles... That just pains me to look at! :lol:

That was the original CG-5 on its flimsy aluminium tripod using the Vixen Skysensor goto system (first one commercially available)
No worries about shake as top speed would have the mount do a 180° slew in about 15 minutes :lol:
They were not fast.

Well, it's not collapsing in the pic, but I wonder what the load rating is on that tripod. Looks rather spindly to me. Almost looks like the counterweights alone would max it out. Meh, maybe I'm just a Nervous Nelly.

It looks like the tripods is tightened up quite well. I imagine it would hum like a guitar string if tapped.
The mount was capable of 25lb but the tripod was barely adequate for that.
Celestron received a huge backlash about it and within a few months the now standard 2" stainless steel tripod was available.

Back about 19 years ago or so, I bought a CR-150HD achromatic refractor on that same mount. The refractor was excellent for a 150mm f/8 achro. The mount was terribly shaky, but usable in calm conditions. I sold the mount and tripod on AM after less than two years, and bought an Atlas EQ from Orion. That Atlas mount was perfect for the scope. I kept it until early 2019, when I sold the scope, then the mount. Replaced with a ES 152 F/8 apo in CF tube on a Losmandy G11. Better all around.

I still have the Vixen Skysensor 2000 working on a GPDX mount, mounted on a pillar.
:character-oldtimer: Almost antique by now. Like me. Still working. Had to change the internal battery two years ago.
It is not fast, but I am not in a hurry. :D
I have set the speed- rate at 0,5 of its capacity :lol:
No shaking, I am glad it is moving :laughing-rolling:

one thing is certain this rig is not on steroids.
but it's better than having nothing to look at the sky.

Hook it up to your motocycle gearbox, that should speed it up! :D

I'll bet the combo of that spindly tripod and that focuser really make for an interesting session.:)

Most likely more stable than the strangely shaped factory adapter that is only held by one screw.

Looking at it again, it may be two electric conduit clips bolted together.
If it holds everything tightly I would say job done.
