Mark is on the right track. There is no reason not to stay in your own home and use home care facilities. I will still have access to my observatory if a mobility scooter can get me out there. And there is always video astronomy, which is really leaping ahead with the new high frame rate cameras. If your system is automated you can lie in bed and watch the GRS transit, through your gear. It may not be exactly the same as staring into an EP but be aware by that time your vision is likely to be terrible, with age related macukar degeneration, lense yellowing or cataracts, etc.
