Faint object near 8.5 mag star, which makes acquisition difficult.
Elongated halo, E-W, mostly seen with AV. Even brightness; no center
stellaring, but there are subtle twinkles of light throughout halo. At
130x there is a slight flare of brightness near core. |

At 73x, small, intense, and complex oval/
circular halo. Very textured. Just SE of two bright (7.5 mag) stars,
with another faint (13 mag) star near edge of halo to W. At 168x, disk
shows spiral texture, margins very distinct. Hint of a bar (?) or
elongation N-S. |

At 73x, S of 12 mag star, which makes it
difficult to define. At 168x with AV, smooth elongated halo with
another faint star just to SE. Smoothly brighter toward center;
no stellaring; outer margins fade out gradually to background. |

Fairly bright and very irregular halo at
130x. At 168x, some core brightening and nucleus looks stellar at
times. Out margins very ragged; spoke-like areas, but general shape is
oval elongated SW-NE. At 235x, core area is very clumpy; dark region
embedded in core to SE. Tends to flare into more elongated shape with
AV. |

In 14mm (168x), seen behind 11-12 mag
star, which is within oval-round halo. Smooth surface with only slight
granularity and no stellaring. Margins indistinct, and effect
increased by the foreground star. At 73x, halo seen as even glow with
AV. |

Star like, bright, at 73x. At 130x,
smooth, oblong halo with only slight brightening at core. At 235x,
core is brighter, slightly knotty, with central bulge. Ends extend out
in wispy points oriented N-S. E side more distinct. |
