A uniform oval halo aligned NW-SE. It brightens rather abrubtly to a
fairly bright diffuse core. Visible with direct vision at 77x, it bore
magnification well and was best seen at 257x. The galaxy is neatly
centered inside a diamond shaped asterism consisting of 4 12th magnitude
field stars which are themselves aligned N-S and E-W. NGC5813 is located
inside the same 77x (29') field with NGC5806.
