At 73x, small, elongated halo with stellar nucleus. With AV, extending
arms very slender, well defined, oriented SE-NW. At 268x, bright core
area with several knots of brightness -- central bulge very apparent.
12+ mag star to the N, aligned with disk. |

M-104. At 168x, elongated halo. Very
bright with stellar nucleus and length-wise mid-core dark streak very
evident (dark lane.) At 73x, tips of disk are very wispy, central
bulge very much brighter. Good view for this seeing. |

Round but irregular disk with stellar
nucleus at 73x, just W of two 12+ mage stars. At 268x, there is
another very faint star on edge of disk to SE. Stellaring maintained
at higher power, but winks on and off with AV. Core area pretty well
defined, but surrounding halo very dim. Core fairly smooth, except for
nucleus. |

At 73x, very large edge-on spiral,
oriented E-W, with 13 mag star in center of N edge long-wise. Some
mottling in central bulge/ core region. Fills 1/3 of 32mm field! At
168x, length-wise margins are scalloped. Some mottling across disk,
but mostly smooth. Ends are rounded. No obvious stellar nucleus; edge
toward star more sharply defined. |

Bright round ball at 130x. Core area
shows fairly even brightness. At 168x, core area very large, with
increasing evenly to central point. Between two dim (~13 mag) stars,
one to NE & the other (dimmer) to SW. AV shows extended halo which is
slightly oval NW-SE. |

Acquired at 168x. Bright almost circular
halo, with 12 mag star to NW. Nuclear flare or stellaring. margins of
core area are very distinct with DV, but halo enlarges considerably
(~40%) with AV. At 235x, halo not visible, but oval core has
considerable granularity and retains nuclear brightening and stellar
point. At 73x, very small with stellar center. |

into smooth, oval-round ball with bright stellar center and soft but

at 235x: bright flare toward nucleus and core is more elongated and
irregular (hint of a bar?) Halo expands considerably with AV and
central brightening increases. |
