Brian, deeply sorry about the MS, from the MS sufferers I've met it seems like what I went through with my stroke only in reverse
I had my stroke 3yrs ago and had to adapt my astronomy/photography to suit my current reduced condition. Where I've settled is I have my nikon with 70-200mm lens permanently focused for astro and mounted on a camera tripod with a ball head and trigger grip. As I only have one hand to use this gives me enough control to point where I need and I found a red dot finder with hot shoe mount to put on top to help me aim easily from a seated position ( i was lucky and beat the wheelchair). So i got help adjusting the height of the tripod and cant use the eye viewer anyway, so its red dot and live view to help align. it's a light enough setup to move around. I also have a pana fz1000 on a vixen polarie on another tripod for longer tracking (my nikon is too heavy for the polarie so gave up on a tracking solution with that for now).
Telescopewise I downsized to the celestron skyprodigy 6 . Even in suburbia this does a reasonable job of auto aligning and tracking for me to use my zwo imager. I found on ebay a tripod dolly which I have the skyprodigy on, basically just gives it wheels so I can have it set up in the garage and wheel it outside, no heavy lifting issues but the foot brakes can be tricky for me and the slope out front too. The accessory tray on the tripod I got help to glue/tie a board onto this and the legs firmly so it came out one side to form a ledge I could sit my laptop on to capture. The tripod dolly also forms three radiating beams out to the base of each tripod leg where they are affixed above the wheels. This gave me a flat frame a few inches above the ground for me to put my battery pack for the scope , So the whole thing I have permanently ready to go, just need to wheel it outside. I can do what I need indoors to charge battery and fiddle with laptop data to an portable drive to take to my pc and get someone to help me if any part of it feels lose to help with cable ties etc. The 6in SCT isnt mind blowing but its a very usable setup for someone living alone with a disabillity to manage safely on my own. Happy to send you some pics over the weekend if you like, send me a private message with email.
It's a setup that would be adaptable to most telescope on tripod mount setups. Its stable and above all as portable in one trip to be up and running. Not transportable though, not as impressive as many setups here but its allowed me to continue enjoying astronomy when I thouhgt it was beyond me. My only thoughts on change are either modding a lid to make a wider focuser wheel to help focusing better or try to find a dual speed focuser that will work in this OTA (not something i can currently afford to try anytime soon though). You're not alone in your struggles mate, you may not get back to where you were but you don't have to quit entirely either, it was hard for me to compromise and i still have my scopeasaurus 11" SCT and still dream of getting a motorised wheeled method I can put it on to be able to use it again, observatory not an option for my place sadly.

I found it best to use a telrad circle finder on my scope, not just because they are awesome but because they are ugly and stand up high. I have balance problems and motor control problems just bending so using eyepiece and red dot finders i find difficult. a 45deg diagonal might help.
