not pronounced. At 150x, curved threads of light appear in halo. 14+

At 80x, four dim stars in
an "X" pattern with background granularity, just NE of a pretty red
star. At 150x, haze resolves in several areas to very dim stars
(14+ mag) esp. to SE. Red star is revealed to have a dim (averted
vision) companion. |
