Found with the help of Skychart software (it does not appear on Wil Tirion's Sky
Atlas 2000.0). At very low powers (*23) seen as a small, faint "ghost" in the
brink of needing averted vision to spot it. 

Increasing power up to *79, it appears as a small oval elongated N-S with
diffuse edges, bright center, and certain gradient, resembling me a small and
much fainter version of M49 (yes, I know there's one Virgo cluster (the S zone)
report pending; I'll try to post it soon).

Not so impressive as Virgo's galaxies -and much less than Andromeda seen that
night; I'll also post her report soon-, but we're talking of a giant elliptical
galaxy that outshines Virgo's brightest ones at roughly 500 million light years;
she may be well one of the farthest objects seen with a very small telescope.
