Not even with a 2.5 meter or larger telescope? Yes, interested
amateurs can rent the Hoover telescope.

The Hooker telescope? Yes, I've observed through it visually. However,
even with a newly re-aluminized 2.5 meter telescope, magnitude 6
skies, a large pupil, high power, and good seeing it's doubtful even
an expert observer would see a mag 19 star. But not impossible.

Still, short of the rare opportunity to take advantage of a huge
aperture instrument under ideal conditions, I think it's safe to say
this object is out of visual reach of amateur astronomers (even if
it's easily imaged).

Indeed. Pluto was a tough object for me under 6th magnitude skies
using a 12.5 inch newtonian. Had to verify it amongst the star
field over the course of several days.
