I have limited, albeit not recent, experience with imaging.
An existing fixed pier is available, as are a number of OTAs including Celestron C8 SCT and Skywatcher 10" newtonian, as are CGEM-DX (tuned by DarkFrame) and an AVX.
This is a pre-retirement purchase, so, I am looking for something I will not need to consider upgrading in the reasonable far future.
An observatory is in planing stages, well, I am comparing dome vs ROR, with a preference for the latter.
I have a budget that would allow purchase of the iOptron CEM120 C2

Am looking for equivalents, or better, in the price range.
