At 73x, fairly large elongated halo, studded with 4-5 dim field stars.
At 130x, halo margin is more distinct on S edge. N edge fades out
gradually, as do ends. |

At 73x, larger and brighter than 3708,
which is just to the N. Round with smooth brightening toward center.
At 168x, stellar nucleus surrounded by granular halo, which is
slightly oval, E-W. Triangular group of faint stars just to E. Halo
has somewhat distinct, but tenuous outer margins. With AV, halo fills
in, but margins don't expand very much. More elongated and much
dimmer NGC 3599 is glimpsed with AV to the W. |

Smaller and a bit more elongated than

Very slight brightening toward nucleus. Texture fairly smooth;
brightens with AV very much. Hint of a bright concentric portion
detached from center on N margin. With extended viewing, nucleus
becomes stellar at times. |
