Hershel 400 Objects in Corvus
| Abbreviations in the CON column are the IAU versions. |
| The column TYPE has following abbreviations: |
| OPNCL = open cluster |
PLNNB = planetary nebula |
GLOCL = globular cluster |
CL+NB = open cluster and nebulosity |
BRTNB = bright emission or reflection nebula |
| Hubble Classification for galaxies or GALXY where no
classification existed. |
| In the Herschel Column
the Classes are: |
| I = Bright Nebulae |
III = Very Faint Nebulae |
V = Very Large
Nebulae |
VII = Pretty Much Compressed
Clusters of Large or Small Stars |
| II = Faint Nebulae |
IV = Planetary Nebulae |
VI = Very Compressed and Rich Clusters
of Stars |
VIII = Coarsely Scattered

H II 296 |
Pretty faint, large, elongated 1.5 X 1 in PA
110 and much brighter in the middle at 220X. This galaxy exhibits
some nice mottling in the outer section. What I found bizarre is that
the central core of this galaxy is elongated in PA 75, much different
from the angle of elongation of the main galaxy. I cannot think of
another example of an object with a bright core that is skewed in
relation to its' main body. |

H IV 28 |
Pretty bright, pretty large, irregularly round
and somewhat brighter in the middle at 100X. Going to higher powers
reveals some of the bizarre nature of this extraordinary galaxy pair.
The "shrimp" or "comma" shape of the two interacting
galaxies is evident at 165X and 220X. There are several small dark
features seen and the entire galaxy pair is very mottled, almost like
a sponge, at high power. |

H I 65 |
Bright, large, somewhat elongated (1.5 X 1)
in PA 90, grey in color at 135X. The central star is obvious at all
powers. Going to 220X brings out an almost "mottled" effect
across the face of this planetary nebula, a strange effect for this
type of object. Most planetaries I have seen appear smooth at high
powers, this one does not. |
