At 130x, seems to have two bright components & stellar center. At 235,
halo elongated slightly E-W; center brightness blinks on and off with
AV; outer margins irregular. |

Acquired at 73x as small patch with no
texture or light variation within elongated halo. At 268x,
bright oval oriented SW-NE just W of 13 mag star. Disk has smooth
texture, with no stellaring; outer margins fairly distinct. Two 11 mag
stars to the NW in 14mm field. Just N of 5576. |

Looks stellar at 723x. At 168x, only
slightly oval, but becomes more elongated (E-W) with AV. Very faint
(13+ mag) star to NW. Nucleus looks stellar at times in the middle of
a very small, sharply defined core region. Outer margins even but
indistinct. |

Small oval disk with brighter center at
73x. Round halo expands evenly around core with AV. At 168x, effect of
DV=elongated, AV=round is greater. Takes higher mag well. Stellar
nucleus at 168x. Core is flare-like toward center; outer margins fade
out gradually. |

At 168x, round halo sitting just W of
9-10 mag star. Flare of brightness at core, with subtle spoke forms,
but no resolution. At 235x, shape is more irregular, with some
granularity; spokes more obvious. A few stellar points with AV at
times, though it almost disappears with DV at times. |

N of two 11 mag stars. Very small at 73x,
with some brightening toward center. At 235x, core is granular, with
bright spokes trailing out to NE and SE. Just beyond resolution with
DV. With AV, some areas appear to resolve. There is another 12+ mag
star to E. margins to E are more distinct. To W, body of cluster fades
out a bit more smoothly. |

At 73x, very elongated halo, oriented
generally N-S, just to SE of 9 mag star, which is just off the edge of
halo. At 168x, halo looks fatter, but no stellaring at nucleus. E
margin pretty distinct, W less so. Hint of granularity in disk & core
area (central bulge?) is a bit brighter than extended arms. |

between two 11+ mag stars. Smoothly brighter toward center; sharply
distinct outer margins. At 168x, bright central bulge, with ends
trailing out to points with AV. Ends seem to curl back on themselves slightly. |
