Under $10k.
I can leave it on mount in the observatory, so I don't have to move it (well once to mount it).
Have been looking at ODKs at f6,8 (fl 1700mm). Then there are the usual Newt suspects. I am constrained by swing room in the Obs but think I could get a 12" f5 under the roof ok (and that could be a cheap solution), but only 1500mm fl. A 16" would not fit at all.
